age, a Bahand will last 6.3 days from the time it is purchased in the store to the time it is too rotten to eat. Is the mean time to spoil different if the banana is hung from the ceiling? The data show results of an experiment with 15 bananas that are hung from the ceiling. Assume that that distribution of the population is normal. 5.5, 3.9, 3.9, 5.7, 6.5, 5.9, 3.9, 7.4, 4.3, 5.9, 4.5, 4.2, 7, 5.1, 4 What can be concluded at the the a = 0.05 level of significance level of significance? a.

search A study was conducted that resulted in the following relative frequency histogram. Determine whether or not the histogram indicates that a normal distribution could be used as a model for the variable. Yooo Choose the correct answer below. OA. The histogram is not bell-shaped, so a normal distribution could be used as a model for the variable. OB. The histogram is not bell-shaped, so a normal distribution could not be used as a model for the variable. OC. The histogram is bell-shaped, so a normal distribution could not be used as a model for the variable. OD. The histogram is bell-shaped, so a normal distribution could be used as a model for the variable. ly 144 is 4+ 2000 3000 4000 Q Q G 5000 prt sc delete
DATAfile: Costco You may need to use the appropriate technology to answer this question. Consumer Reports uses a 100-point customer satisfaction score to rate the nation's major chain stores. Assume that from past experience with the satisfaction rating score, a population standard deviation of ? = 13 is expected. In 2012, Costco, with its 432 warehouses in 40 states, was the only chain store to earn an outstanding rating for overall quality. A sample of 15 Costco customer satisfaction scores follows. 95 90 83 75 95 98 80 83 82 93 86 80 94 64 62 (a) What is the sample mean customer satisfaction score for Costco? (b) What is the sample variance? (Round your answer to two decimal places.) (c) What is the sample standard deviation? (Round your answer to two decimal places.) (d) Construct a hypothesis test to determine whether the population standard deviation of ? = 13 should be rejected for Costco. With a 0.05 level of significance, what is your conclusion?…
