Solution
7)
Here we given that,
df = 100
If one sided test t0.05,100 = 1.66
If two sided test t0.025,100 = 1.984
8)
P-value < or Test statistic > critical value then Reject the null hypothesis .

1.You are performing a left-tailed z-test If α=.005α=.005, and your test statistic is z=−2.59, do you: Reject Null Hypothesis Fail to Reject Null Hypothesis You are performing a left-tailed z-test If α=.10, and your test statistic isz=-2.01, do you: Reject Null Hypothesis Fail to Reject Null Hypothesis You are performing a right-tailed t-test with a sample size of 15 If α=.01, and your test statistic is t=3.02t=3.02, do you: Reject Null Hypothesis Fail to Reject Null Hypothesis You are performing...
You are performing a left-tailed t-test with a sample size of 21. If α=.05α=.05, and your test statistic is t=−2.89t=-2.89, do you: fail to reject the null hypothesis reject the null hypothesis You will either want to either: Calculate the critical value and compare the test statistic to it. Calculate the p-value and compare it to the significance.
For the folowing claim, find the null and alternative hypotheses, test statistic, critical value, and draw a conclusion. Assume that a simple random sample has been selected from a normally distributed population. Answer parts a-d. Claim: The mean IQ score of statistics professors is less than 119.

Suppose that, for a t-test, your computed value for t is +3.28. The critical value of t is +2.048. Explain what this means. Do you reject the null hypothesis or not? Now suppose that you have 28 degrees of freedom and are using a two-tailed (nondirectional) test. Draw a simple figure to illustrate the relationship between the critical and the computed values of t for this result.

1) Identify the rejection point(s) for the test of the following hypothesis: H0: mean = 10, Ha: mean != 10 Conducted on a sample size of 15, on a normally distributed population with unknown population variance, and a desired Type1 error probability (alpha) of 0.05. Hint: use the appropriate statistical function in your spreadsheet to determine the rejection point. Z test with rejection points -1.64 and +1.64 Z test with rejection points -1.96 and +1.96 t-test with degrees of freedom=14,...
QUESTION 11 You run an independent samples t-test between two groups, and find a t-statistic of t=1.67. Is this sufficient to reject the null hypothesis? Assume α=0.05 and a one-sided test. Yes, > 1.67 is sufficient to reject the null. No, > 1.67 is not sufficient to reject the null. Not enough information. 2 points QUESTION 12 In a dependent samples t-test, the sample sizes must be equal. True False 2 points QUESTION 13 In an independent samples...
