What is the smallest alpha that you CAN reject the null hypothesis under when you have a p-value of .049?

A sample has a mean of M = 39.50, a standard deviation of s = 4.30, and produces a t statistic of t = +2.14. For a two-tailed hypothesis test, which of the following is the correct statistical decision for this sample? A. The researcher should reject the null hypothesis with α = .05 but not with α = .01. B. The researcher should reject the null hypothesis with either α = .05 or α = .01. C. The researcher should reject the null hypothesis with α = .01 but not with α = .05. D. This is impossible to determine based on the provided information.

If, in a sample of n = 25 selected from a normal population, X = 57 and S= 10, what is the value of tSTAT if you are testing the null hypothesis Ho: μ = 50? tSTAT = (Type an integer or a decimal.)

Suppose that we have a problem for which the null and alternative hypothesis are given by: H0: μ = $1250. H1:μ ≠ $ 1250 Is this a right-tailed test, left-tailed test, or two-tailed test. Find the z value based on a level of significance of α=.12.

Suppose in a hypothesis testing, we obtained a pp-value of 0.003.  Which of the following is/are FALSE about pp-value?  A. If Type I error rate is set at 0.05, we can reject the null hypothesis.  B. We cannot reject the null hypothesis if we set αα to 0.001. C. This pp-value indicates that there is a small chance that that the null hypothesis is true. D. This pp-value indicates a big effect size. E. B and C F. C and D

If, in a sample of n = 16 selected from a normal population, X= 51 and S = 8, what is the value of tSTAT if you are testing the null hypothesis Ho: µ= 50? tSTAT = (Type an integer or a decimal.)

Laura asks whether the type of school students attend (private versus public) results in different performance on a test. A sample of N=100 students from a private school produce a mean of 71.30 on a test, and the mean of the population of public school students is µ=75.62 with ?௫ =28. a. Write the alternative hypothesis. b. Write the null hypothesis. c. With α=.05, what is zcrit? d. Compute zobt e. What should Laura conclude?

What is the​ p-value if, in a​ two-tail hypothesis​ test, ZSTAT=+1.56​?       ​p-value= _______ ​(Round to four decimal places as​ needed.)

Suppose there is a claim that a certain population has a mean, μ, that is different than 6. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis, Ho, and the alternative hypothesis, H₁, as follows. Ho: μ = 6 H₁: μ #6 Suppose you also know the following information. The value of the test statistic based on the sample is 1.518 (rounded to 3 decimal places). The p-value is 0.129 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test. Standard Normal Distribution Step 1: Select one-tailed or two-tailed. O One-tailed OTwo-tailed Step 2: Enter the test statistic. (Round to 3 decimal places.) Step 3: Shade the area represented by the p-value. Step 4: Enter the p-value. (Round to 3 decimal places.) 0.3 0.2 0.1-

If the hypothesis test results in a p-value of 0.08 would we be able to reject the null hypothesis using an alpha of 0.10?   Question 3 options:   yes   no   need more information to decide
