Consider the following hypotheses: H0: μ-360 The population is normally distributed with a population standard deviation of 73. (You may find it useful to reference the appropriate table: z table or t table) a-1. Calculate the value of the test statistic with x = 389 and n = 80, (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Test statistic a-2 what is the conclusion at the 10% significance level? Do not reject...

(1 point) The sample mean and standard deviation from a random sample of 33 observations from a normal population were computed as x¯=34 and s = 10. Calculate the t statistic of the test required to determine whether there is enough evidence to infer at the 6% significance level that the population mean is greater than 30. Test Statistic =

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...
