We would like to conduct a hypothesis test to determine whether the true mean rent amount for all one-bedroom apartments in Winnipeg differs from $850. We take a random sample of 50 one-bedroom apartments and calculate the sample mean to be $900. A 98% confidence interval for μ is calculated to be (830, 970). The conclusion for our test would be to:

In order to conduct a hypothesis test for the population mean, a random sample of 24 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 6.3 and 2.5, respectively. (You may find it useful to reference the appropriate table: z table or t table). H0: μ ≤ 5.1 against HA: μ > 5.1 a-1. Calculate the value of the test statistic. (Round all intermediate calculations to at least 4 decimal...

We would like to conduct a hypothesis test at the 2% level of significance to determine whether the true mean pH level in a lake differs from 7.0. Lake pH levels are known to follow a normal distribution. We take 10 water samples from random locations in the lake. For these samples, the mean pH level is 7.3 and the standard deviation is 0.37. Using the critical value approach, the decision rule would be to reject H0 if the test...

. We would like to conduct a hypothesis test at the 10% level of significance to determine whether the true mean score of all players in a bowling league differs from 150. The mean and standard deviation of the scores of 12 randomly selected players are calculated to be 170 and 16, respectively. Scores of all players in the league are known to follow a normal distribution. The P-value of the appropriate test of significance is
