The health of employees is monitored by periodically weighing them in. A sample of n = 54 employees has a mean weight of x̄ = 190 lb. Assuming that σ = 25 lb, use a 0.01 significance level to test the claim that the population mean of all such employees weights is less than 200 lb. Group of answer choices a. H0: μ = 200; H1: μ < 200; Test statistic: z = -2.94. P-value: 0.0016. Since the P-Value is...

1. Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. Choose the best conclusion. The owner of a football team claims that the average attendance at games is over 523, and he is therefore justified in moving the team to a city with a larger stadium. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms. a....

A recent broadcast of a television show had a 10 share, meaning that among 5000 monitored households with TV sets in use, 10% of them were tuned to this program. Use a 0.01 significance level to test the claim of an advertiser that among the households with TV sets in use, less than 15% were tuned into the program. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original...

A recent broadcast of a television show had a 1010 share, meaning that among 60006000 monitored households with TV sets in use, 1010 % of them were tuned to this program. Use a 0.01 significance level to test the claim of an advertiser that among the households with TV sets in use, less than 1515 % were tuned into the program. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses...
