Given the following hypothesis: H0 : μ ≤ 12 H1 : μ > 12 For a random sample of 10 observations, the sample mean was 14 and the sample standard deviation 4.80. Using the .05 significance level: (a) State the decision rule. (Round your answer to 3 decimal places.) (Click to select)Cannot rejectReject H0 if t > (b) Compute the value of the test statistic.

The following hypotheses are given. H0 : π ≤ 0.83 H1 : π > 0.83 A sample of 100 observations revealed that p = 0.87. At the 0.10 significance level, can the null hypothesis be rejected? State the decision rule. (Round your answer to 2 decimal places.) Compute the value of the test statistic. (Round your answer to 2 decimal places.) What is your decision regarding the null hypothesis? Do not reject H0. Reject H0. question 2: The number of...
(a) Suppose the null and alternative hypothesis of a test are: H0: μ= 9.7 H1: μ >9.7 Then the test is: left-tailed two-tailed right-tailed (b) If you conduct a hypothesis test at the 0.02 significance level and calculate a P-value of 0.07, then what should your decision be? Fail to reject H0 Reject H0 Not enough information is given to make a decision
The following hypotheses are given. H0 : π ≤ 0.81 H1 : π > 0.81 A sample of 80 observations revealed that p = 0.95. At the 0.01 significance level, can the null hypothesis be rejected? State the decision rule. (Round your answer to 2 decimal places. Reject H0 if z > Compute the value of the test statistic. (Round your answer to 2 decimal places.)
Use the following information for the next 3 questions: Suppose you want to test for whether there is a difference in starting salaries for those with a finance degree compared to those with an accounting degree. You sample 35 graduates with a finance degree and find the average starting salary to be 58,000 with a sample standard deviation of 5,000. You also take a sample of 40 graduates with an accounting degree and find the average starting salary 56,000 to...

2.If your decision for the hypothesis test you performed
for Problem 1 was incorrect, what type of error would it be (Type I
or Type II)? Explain what this error means in the context of this
situation.
Suppose you want to test the following hypotheses: H0: p ≥ 0.4 vs. H1: p < 0.4. A random sample of 1000 observations was taken from the population. Answer the following questions and show your Excel calculation for each question clearly: (a) Let p ̂ be the sample proportion. What is the standard error of sample proportion (i.e., σ_p ̂ ) if H0 is true? (b) If the sample proportion obtained were 0.38 (i.e., p ̂=0.38), what is its p-value?...
