A USA based cable broadband company wants to compare the average customer satisfaction scores betweenits east coast and west coast customer bases. The customer survey asks for a score between 1 and 5, with 1being poor and 5 being excellent.174 east coast customers are surveyed, and the sample mean is 3.51 with a sample standard deviation (s) of0.51. For the west coast, 355 customers are surveyed, and the sample mean is 3.24 with a sample standarddeviation (s) of 0.52. Create a 95% confidence interval for the true average score for west coast customers.What is the UPPER limit of the confidence interval?Round to the nearest 3rd decimal place, x.xxX

Standard Deviation (s) = 0.52 Sample Size (n) = 355 Sample Mean (x̄) = 3.24

The average McDonald's restaurant generates $2.4 million in sales each year with a standard deviation of 0.7. Carissa wants to know if the average sales generated by McDonald's restaurants in New Mexico is different than the worldwide average. She surveys 18 restaurants in New Mexico and finds the following data (in millions of dollars): 2.1, 2, 2.9, 1.7, 1.8, 2.3, 2.1, 2.1, 3.3, 1.4, 1.6, 1.4, 1.4, 2.3, 2.6, 2.7, 2.7, 1.7 Perform a hypothesis test using a 8% level of significance. Step 1: State the null and alternative hypotheses. Ho: pv 2.4 Ha: Ev 2.4 (So we will be performing a two-tailed test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are normally distributed v with and distribution standard deviation distribution mean Step 3: Find the p-value of the point estimate.

The U.S. Center for Disease Control reports that in year 1900, the mean life expectancy is 47.6 years for whites and 33 years for nonwhites. (Click here for reference data ) Suppose a survey of randomly selected death records for white and nonwhite people born in 1900 from a certain county is conducted. Of the 117 whites surveyed, the mean life span was 46.7 years with a standard deviation of 11.4 years and of the 86 nonwhites, the mean life span was 38.4 years with a standard deviation of 15.4 years. Conduct a hypothesis test at the 0.1 level of significance to determine whether there was no difference in mean life spans in the county for whites and nonwhites in year 1900. Preliminary: a.

The producer of 500 mg Vitamin C tablets finds that the actual Vitamin C content in their tablets is normally distributed with mean 491 mg and standard deviation 15 mg. What proportion of Vitamin C tablets contain less than 500 mg? Answer: The manufacturer decides to discard all tablets in the bottom 2.5% of Vitamin C content. In a production run of 100,000 tablets, how many will be discarded? What is the Vitamin C content cut-off value (round to one decimal) that determines if a tablet is discarded? mg

In a sample of 351 gamers between the ages of 16-25, the mean number of hours spent gaming per week was 42.5 hours. In a sample of 269 gamers between the ages of 26-40, the mean number of hours spent gaming per week was 43.8 hours. If the population standard deviation for the mean number of hours spent gaming per week is 9.5 for the age group 16-25 and 10.7 for the age group 26-40, test the claim that gamers between the ages of 16-25 spend less time gaming per week than gamers between the ages of 26-40. Assume α=0.03. Let population 1 be gamers in the age group 16-25 and population 2 be gamers in the age group 26-40. Round the test statistic to two decimal places, and round the p-value to four decimal places. The test statistic is . The p-value is . Should the null hypothesis be rejected?
