Create a program called ResortPrices that prompts the user to enter the
number of days for a resort stay. Then display the price per night and the total
price. Nightly rates are R 500.00 for one or two nights, R 650.00 for three or
four nights, R 850.00 for five, six or seven nights, and R 1500.00 for eight
nights or more.

3. Compute the range and interquartile range.
4. Compute the variance and standard deviation.
5. The skewness measure for these data is 0.34. Comment on the shape of this distribution. is it the shape you would expect? Why or why not?

3. Based on historical data, your manager believes that 25% of the company's orders come from first-time customers. A random sample of 114 orders will be used to estimate the proportion of first time-customers. What is the probability that the sample proportion is less than 0.29?
   
   Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's approach and calculations.
   
   Answer =  (Enter your answer as a number accurate to 4 decimal places.)

Suppose that 8 cards, of which four are red, two are green and two are blue, are placed at random in 8 envelopes . Two envelops are selected at random,

1. find the probability that the envelops have red cards?
2. find the probability that they have cards of the same colors?

In the past, Dumont Clothing Store had 72% charge purchases and 28% cash purchases. A representative sample of 200 recent purchases shows that 160 were charge purchases. Does this suggest a statistically significant change in the paying practices of Dumont customers?

The n th Triangle Problem Write a code for finding the n th triangle number of triangle sequences: 1, 3, 6, 10, ..., n. That is, your code should accept an integer number, which indicates the triangle levels, and returns how many dots we need to form a triangle with respect to the given level. For example, consider the Fig 1. For n = 3 (can be also written as T3), your code should returns 6.

Provide a single program consists of the following:

• Write a function called TriangularRecursive for the recursive version that takes number of level as an int argument.

Hints:

1) Identify the base case for the TriangularRecursive function.

2) Let the TriangularRecursive function call itself, with proper arguments.

• Write a function called TriangularIterative for the non-recursive (iterative) version that takes number of level as an int argument.

• Write a main function that calls the two functions inside. You should have at least a couple of test cases included in the main function that shows the output for both functions.

After implementing the recursive and non-recursive functions, you are supposed to perform two additional tasks. The first task is to analyze both approaches as follows:

• Establish the recurrence relations for the recursive approach.

• Solve the recurrence and provide the order growth.

• Establish the sum expression for the non-recursive approach.

• Solve the sum and provide the order growth.

The second task is to plot the running time of both approaches for different input sizes (n). To do that, consider ten input size (n) values: 10, 50, 100, 200, 400, 800, 2000, 4000, 8000, 10000. For better precision, run each value ten times and take the average of all ten runs for each case.

5. Your statistics professor is involved in an educational outreach program designed to increase women’s participation in science, technology, engineering, and mathematics (STEM). The two-week educational program involved fieldtrips and activities designed to increase participants’ knowledge toward STEM.

On the first day of the education program, a pre-test is administered to all students. On the final day of the educational program, an identical post-test is administered. After the educational program ends, your professor asks you to help her analyze the results. Your professor predicts that pre- and post-test scores will differ significantly and wants to use an alpha level of 0.01. (50 Points)

1. Are you running a one-tailed or two-tailed test?

2. Write your alternative and null hypotheses.

3. Which statistical analysis will you use to run your test (e.g. one-sampled t-test, an independent-samples t-test, a paired t-test, or chi-square test)?

4. Run your statistical analysis using SPSS. Write your conclusion.

(Remember, if you are running a one-tailed test, your alpha value is located in one-tail, meaning your p-value needs to be less than 0.01 to reject the null hypothesis.

If you are running a two-tailed test, your alpha value is divided in half, meaning your p-value needs to be less than 0.005 to reject the null hypothesis)

Above are two readings of systolic and diastolic blood pressures taken from 15 individuals. Test the hypothesis that there is a significant difference between the first and second readings for systolic blood pressure (both sexes combined), with an α of 0.05. What test would be most appropriate and why? Is the result significant? State your conclusions.
