Step 1:
Number of jobs created per month graduation.
Step 2:
The null hypotheses is:
We need to test whether this claim is correct or not so alternative hypothesis will be

Hypothesis Problems For the following hypothesis tests: a. State the null (Ho) and alternative (Hi) hypotheses b. State the type of test (right-tailed, left-tailed, or two-tailed) c. State the multiplier for an a (level of significance) of .05. The Chamber of Commerce states that only 15% of Boston tourists stay more than 2 days. A new chamber employee feels that the percentage staying more than 2 days is greater than 15%, and plans to sample a set of tourists to...
State the null and alternative hypotheses for a hypothesis test; indicate whether the hypothesis test will be left-tailed, right-tailed, or two-tailed; and clearly state the two possible conclusions that address the given claim. 15. A medical researcher wants to test the claim that healthy adults have a mean body temperature less than 98.6°F.

The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Null Hypothesis: Alternative Hypothesis: Notice that the alternative hypothesis is a one-tailed test. Suppose ttest_ind method from scipy module is used to perform the test and the output is (3.25, 0.0043). What is the P-value for this hypothesis test? Select one. Question 2 options: 3.25 -3.25 0.0043 0.00215

Step 4 of 10 : Find the expected value for the number of service calls received on Monday. Round your answer to two decimal places. Step 5 of 10...
State the null and alternative hypothesis for a hypothesis test; indicate whether the hypothesis test will be left-tailed, right-tailed, or two-tailed; and clearly state the two possible conclusions that address the given claim. vending machines. A sales representative claims that quarters inserted into her vending machines have a mean weight less than 5.64 grams
The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Null Hypothesis: Alternative Hypothesis: Notice that the alternative hypothesis is a two-tailed test. Suppose ttest_ind method from scipy module is used to perform the test and the output is (-1.99, 0.0512). What is the P-value for this hypothesis test? Select one.
