5 In a hypothesis test for a proportion, the null hypothesis is HO: p = 0.7 and the alternative hypothesis is H1: P = 0.7 with a = 0.05. Then we reject HO if the test statistic Z is 15 (5 Points) between -1.64 and 1.64 and cannot reject H0 otherwise greater than 1.64 or less than-1.64 and cannot reject H0 otherwise between -1.96 and 1.96 and cannot reject HO otherwise greater than 1.96 or less than-1.96 and cannot reject...

Diego is testing a claim about a population mean. The hypotheses are: Ho: u = 137 H: 4 > 137 After taking a simple random sample of 58 subjects, he determines that the sample mean is 140. Diego then does some calculations and writes the following in his notebook: "If Ho were true, the chance that the sample mean would have come out as big (or bigger) than 0.17." What is the name given to the value of 0.17? o...

Consider the following hypotheses: HO: 220 HA u < 220 A sample of 72 observations results in a sample mean of 209. The population standard deviation is known to be 18. (You may find it useful to reference the appropriate table: z table or tablet a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Test statistic...

RReject or not reject each?
Consider the following hypotheses: | Ho: u = 1,600 HA: u 7 1,600 The population is normally distributed with a population standard deviation of 600. Compute the value of the test statistic and the resulting p-value for each of the following sample results. For each sample, determine if you can "reject/do not reject" the null hypothesis at the 10% significance level. (You may find it useful to reference the appropriate table: z table or t...
