Suppose the cost of a VS2 clarity, H color one-carat diamond from Diamond Source USA is $5600. A midwestern jeweler makes calls to a sample of 25 dealers in the diamond district in New York City to see if the average price of diamonds there is greater than $5,600. The price quotes are collected in the data set Diamonds.xlsx, which is in the "Some Datasets" folder on the Contents page. Which of the following is the null hypothesis for the question being investigated by the jeweler? a. Ho: H5600 b. Ho: uz 5600 c. Ho: Hs 5600 d. Ho: H=5600 The correct null hypothesis is given in letter. (Enter the letter only!) d Is this a z-test or a t-test? z A right A Based on the rejection region, this is a "two".) N -test (Enter the letter only!) Question 18 (10 points) 4) Listen -tailed test. (Enter "right", "left", or The critical value that defines the rejection region for the test comes from the ("normal" or "t") distribution.

Based on the rejection region, this is a ________-tailed test. (Enter "right", "left", or "two".) right A Question 18 (10 points) E4Listen The critical value that defines the rejection region for the test comes from the ("normal" or "t") distribution. A For alpha= .01, that critical value equals(Enter the value out to 4 decimal places.) A The value of the test statistic is A/ What is the p-value for this test? . (Enter the value out to 4 decimal places.) (Enter the value out to 4 decimal places.)

Conclusion: The sample data provides evidence to null hypothesis. A/ This indicates that the true mean probably. $5600. A _ ("support" or "reject") the ("is" or "is not") greater than
