A study of the time spent shopping in a supermarket for 20 specific items showed an approximately uniform distribution between 20 minutes and 40 minutes. Bold a. What is the probability that the shopping time will be between 23 and 32 minutes? Bold b. What is the probability that the shopping time will be less than 35 minutes? Bold c. What are the mean and standard deviation of the shopping time? a. The probability that the shopping time will be between 23 and 32 minutes is nothing. (Type an integer or a decimal.) b. The probability that the shopping time will be less than 35 minutes is nothing. (Type an integer or a decimal.) c. The mean of the given uniform distribution is muequals nothing. (Type an integer or a decimal.) The standard deviation of the given uniform distribution is sigmaequals nothing. (Round to four decimal places as needed.)

A study showed that 62% of supermarket shoppers believe supermarket brands to be as good as national name brands. To investigate whether this result applies to its own product, the manufacturer of a national name-brand ketchup asked a sample of shoppers whether they believed that supermarket ketchup was as good as the national brand ketchup. b. If a sample of 100 shoppers showed 51 stating that the supermarket brand was as good as the national brand, what is the p-value...

A study showed that in a certain month, the mean time spent per visit to Facebook was 19.5 minutes.

1. A study showed that in a certain month, the mean time spent per visit to Facebook was 19.5 minutes. Assumes the standard deviation of the population is 8 minutes. Suppose that a simple random sample of 100 visits in that month has a sample mean of 21.52 minutes. A social scientist is interested in knowing whether the mean time of Facebook visits has increased. Perform the hypothesis test and compute the P-value. Based on the P value, what...
