A survey was conducted two years ago asking college students their top motivations for using a credit card. You think this distribution has changed. You randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the distribution? Use a = 0.025. Complete parts (a) through (d). Response Old Survey % 29% New Survey Frequency, f Rewards 110 Low rates Cash back Discounts 23% 96 21% 109 7% 46 Other 20% 64 O B. The distribution of motivations is 110 rewards, 96 low rate, 109 cash back, 46 discounts, and 64 other. O C. The distribution of motivations is 29% rewards, 23% low rate, 21% cash back, 7% discounts, and 20% other.

Out of 57 high school female athletes, data was collected on how much they were able to bench press. From this data we get x=79.9,Q1=70, Q2=80, and Q3=90. Determine if the data distribution is skewed or symmetric. Give 2 reasons to back up your answer.
← A study considers if the mean score on a college entrance exam for students in 2005 is any different from the mean score of 499 for students who took the same exam in 1975. Let u represent the mean score for all students who took the exam in 2005. For a random sample of 40,000 students who took the exam in 2005, x = 497 and s= 100. Use this information to complete parts a through c below. a. Find the test statistic. t = -4 (Round to two decimal places as needed.) b. Find the P-value for testing Ho: μ = 499 against H₂: μ#499. (Round to three decimal places as needed.) The P-value is ...

Español A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of 7.2 ounces of coffee per cup. BIG has good reason to believe that the mean amount of coffee dispensed by the machine, u, is greater than 7.2 ounces, and plans to do a statistical test of the claim that the machine is working as designed. Technicians gather a random sample of fill amounts and find that the mean of the sample is 7.6 ounces and that the standard deviation is 0.5 ounces. Based on this information, complete the parts below. (a) What are the null hypothesis H. and the alternative hypothesis H, that should be used for the test? Ho :0 O
A jeep gets 53 highway miles per gallon. Howvever, an SUV believes gas mileage for their new line is much better. In order to test, they collect a random sample of 8 jeeps. The results of the 8 cars tested as as follows: 56, 51, 55, 54, 57, 48, 56, and 51. If you perform this test at a= .05 level, state the p-value and the conclusion of the test.
