Your friend Maz runs a small shop on Etsy selling homemade knit scarves and beanies. Maz is trying to figure out what they needs to sell before Christmas to earn an operating income of $500. You volunteer to help them figure it out because of all you’ve learned in ACTG 211. Maz provides you with the following information about their business:

What is the weighted average cost per unit? Round answer to nearest penny (x.xx).

How many units does Maz need to sell to breakeven?  Round answer to a whole unit.

How many units does Maz need to sell to achieve their target operating income?  Round answer to a whole unit.

Write a program in C++ that will output the truth table for a simple wff. There will only be Ps and Qs, so you can hard code the P truth table and the Q truth table into arrays. The user will use A for ^ , O for V, N for ' , & I for -> .

Hint: Read the first character, load the appropriate truth table into the first working array. Read the next character. If it is an N, output the negation of the first working array. If it is a P or Q, oad the appropriate truth table into the second working, array, then read the last character and output the appropriate truth table.

Expression                Would be input as

P^Q                            PQA

P'                                PN

Q->P                           QPI

Example runs (note the user input is bold)

Run 1

Please input the wff: PQA

The truth table is

T

F

Run 2

Please input the wff: P'

The truth table is

Eclosion refers to the emergence of an adult insect from an egg. The following data gives eclosion rates when nymphs were exposed to heat for various durations.

Carry out a chi-squared test to decide whether it is plausible that eclosion rate does not depend on exposure duration.
a. State the appropriate hypotheses.

b. Calculate the test statistic value. (X^2)

A researcher wants to investigate the usefulness of hypnotism for reducing levels of anxiety in individuals experiencing stress. He identifies 30 people at random from a group of 100 who have "high stress" jobs. The 30 people are divided into two separate groups. One group of 15 receive the hypnotism. The other group of 15 acts as the control group - they receive no hypnotism. The subjects in each group are then given an anxiety inventory. The results are in the table below, where a higher score means more anxiety.

Please answer all parts to the question

a. Calculate the degrees of freedom.

b. Calculate the difference between the means (M_Hypnotism - M_{No Hypnotism}).

c. Calculate Σχ for the Hypnotism Group.

d. Compute Σχ² for the Hypnotism Group.

e. Calculate Σχ for the No Hypnotism Group.

f. Calculate Σχ² for the No Hypnotism Group.

g. Calculate the Standard Error for this test. Round to two decimal places.

S(χ₁ – χ₂) = ?

f.Calculate the t observed value for this test. Round to two decimal places.

t = ?

g.What is the probability (p) of getting the difference between sample means if the null hypothesis were true? Use Oak Software (NOTE: make sure you input the correct df, select t to p, select the correct area for a left-tailed test, input the correct t value, then press Calculate.

p = ?

h. Based on the results of your analysis, what is your decision regarding the Null hypothesis?

I. Write you conclusion in terms of the effect of hypnotism on anxiety.

Career Training According to the study The American Freshman: National Norms 2015, 76.1% of college freshmen said that “to get training for a specific career” was a very important reason for their going to college. Consider a group of seven freshman selected at random. In Exercises 23–26, find the probabilities that the number of people in the group who felt that the reason was very important is as stated. 23. All seven 24. Exactly three of the seven 25. At least six of the seven 26. No more than two of the seven

You’ve just been promoted to a management position at Worcester Corset Candies Company. Congrats! Immediately, you get a call that Finance noticed a cost variance in your department. It appears that you are consuming too few ingredients for your scheduled output. A box of Special Mixed Corset Candies is supposed to be 140 ounces, and your annual bonus is paid on how close you manage your department’s per/unit costs. To begin analyzing the process, you ask your fill machine operator to record the weights of 9 candy cartons each hour for the next 11 hours. (HINT: Save yourself a lot of time and do this in Excel). Are all points on the R-chart are within the control limits? Are all points on the X-bar chart are within the control limits? So, manager, is your candy making process considered in control?

Does undergraduate success predict graduate success? While most people complete their bachelor's degree during the daytime while taking multiple classes and not working full-time, those getting an MBA are typically taking one or two courses at a time, in the evening or on weekends, and while working and even supporting a family. Yet one would expect those who perform better in their bachelor's degree will perform better in their master's. Using a significance level of .05, test whether there is a correlation between the BS GPA and the MBA GPA. Also, answer the following:

a) What is the correlation coefficient & how strong is it?
b) What is the best fit regression equation that can predict the MBA GPA from the BS GPA?
c) What percent of the variability in the MBA GPA can be explained by the regression model?
d) What would you expect a student's MBA GPA to be if he/she had a 3.50 BS GPA?
