2. Male butterflies sometimes court females of other species with similar wing patterns. You are interested in how long males persist in courting the wrong female. You decide to test each male with a dead female, to control for the effect of the female’s behavior. You use three types of test females: one from the same species as the males, one from a different species with a similar wing pattern, and one from a different species with a different wing pattern. Each pair is placed in a cage, and you measure courtship time in seconds.

Female of same species: 23, 20, 17, 25, 28

Female of different species, similar pattern: 18, 27, 24, 21

Female of different species, different pattern: 22, 21, 23, 20

A consumer preference study compares the effects of three different bottle designs (A, B, and C) on sales of a popular fabric softener. A completely randomized design is employed. Specifically, 15 supermarkets of equal sales potential are selected, and 5 of these supermarkets are randomly assigned to each bottle design. The number of bottles sold in 24 hours at each supermarket is recorded. The data obtained are displayed in the following table.

The Excel output of a one-way ANOVA of the Bottle Design Study Data is shown below.

Find a 95 percent confidence interval for each of the treatment means μ_A, μ_B, and μ_C. Interpret these intervals. (Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign.)

Each of the following statements corresponds (somewhat naturally) to a statistical hypothesis. For each statement, decide

If it involves one or more populations; one or more variables. [No answer needed.]

The population(s) and the variable(s) involved.

The form of the test.

Single parameter

Two parameter or multiple parameter—always the same parameter for multiple populations (or possibly multiple variables)

Single distribution

Two distributions or multiple distributions—either two different variables, or the same variable for multiple populations

Independence

Note with measures of association will have one parameter (g, r, b) with a pair of populations

If the hypothesis is on one or more parameters, give

The parameter(s) involved.

The Null and the Alternate hypotheses. or

Whether the hypothesis test is one or two-sided. or

If the hypothesis is on one or more distributions, give

The Null and the Alternate hypotheses.

Why don’t we need to specify whether one-sided or two-sided?

  AS PER CHEGG POLICY, I CAN ONLY ANSWER THE 1ST QUESTION

  In a mopolistically competitive market, firms are not price takers. They are price makers. So they decide their own price. So in the short run, firms can have supernormal profits. That is they can set any price they want to and get high economic profits. However, since the market is very much price elastic, so unless the product is differentiated, it is not possible to continue this supernormal profits.

  Here we now consider multiple firms whose products are not similar but very near substitutes.

  Now let's say there is a new entrant in the market. The barriers to entry are quite low. So they can easily enter the market. What is the incentive of a new entrant? Since the economic profits are very high, a new firm is enticed to join the market.

  As they join the market, the quantity of products in supply increases. This leads to a lowering of the supply curve. Due to this, the equilibrium price will also go down. Now since the cost of production remains the same, the economic profit of the firm goes down.

  So with each new entry in the monopolistically competitive market, the economic profit of all the firms go down to a point where the economic profit is zero.

  At this point of time, no new firms have any incentive to join the market as they would not get any profit. In spite of that, let us consider that some firm joins. This reduces economic profit from 0 to negative for all the firms. As a result, firms will start to leave the market. If more than one firm leaves, the profits go up and become positive. This creates space for new entries. So the number of firms goes on increasing or decreasing as the case may be till they converge to a optimal number where the economic profit is zero.
  
  
  So if a new firm enters a monopolistically competitive market, in the short run, the economic profits of all the firms decrease and in the long run they become zero.

  Let us consider an example of restaurants. There are many restaurants and infinite customers. The restaurants have priced their food such that they make an economic profit EP. Now there is a new entrant. They price their food lower(to attract customers) and their food is a good substitute of what is available in the market. SO people will start moving to them. Now either they increase prices to reap more profit, or if they have the bandwidth to accomodate the increased rush, they keep on getting customers. This leads to other restaurants to lower their prices as well or face losses. Thus the overall market has a lower price. this means the economic profit for all the firms have gone down.

  Now there is another newer entry at a lower price. So other players can also start undercutting their food prices.

  These new entrants keep on coming and thus prices keep getting lowered till one restaurant has reached the point of Zero Economic Profit. No restaurant will be able to cut prices beyond this point. So All restaurants will converge to this price point to get a level playing field. Thus in the long run, the economic profit becomes zero.

The SAT and the ACT are the two major standardized tests that colleges use to evaluate candidates. Most students take just one of these tests. However, some students take both. The data data297.dat gives the scores of 60 students who did this. How can we relate the two tests?

(a) Plot the data with SAT on the x axis and ACT on the y axis. Describe the overall pattern and any unusual observations.

(b) Find the least-squares regression line and draw it on your plot. Give the results of the significance test for the slope. (Round your regression slope and intercept to three decimal places, your test statistic to two decimal places, and your P-value to four decimal places.)

(c) What is the correlation between the two tests? (Round your answer to three decimal places.)

A researcher is interested in whether the phonics method of teaching reading is more or less effective than the sight method, depending on what grade the child is in. Twenty children were randomly selected from each of three grades: kindergarten (K), first grade (1), and second grade. Achievement was measured in terms of reading comprehension where higher scores indicate better comprehension. Within each grade, 10 children were assigned to each of two methods of teaching reading - phonics or sight. The data are as follows:

                        Grade Levels

                        K         1          2                                              K         1                2

1. State the Null hypotheses for each main effect and interaction – 5 points
2. Present the means and SD for each level of each factor– 5 points.
3. Test the null hypothesis for both main effects and interactions and present the ANOVA source table with all relevant statistics– 15 points.

4. Specify all variables– 5 points.
5. Compute, report and explain results from the HSD post hoc follow-up test– 10 points..
6. Present a graph of the interaction of the two factors– 5 points.
7. Write a statement as to your conclusions– 5 points..

Note. This is a Two-Way ANOVA (i.e., 2 IVs). One IV has two levels and one IV has three levels. Thus, a 2 X 3 ANOVA that will produce 6 cell means, 2 row means and 3 column means.
