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: μ< 5600 b. Ho: μ ≥ 5600 c. Ho: μs 5600 d. Ho: μ = 5600 The correct null hypothesis is given in letter ______.(Enter the letter only!) d Is this a z-test or a t-test? 2 A/ right Based on the rejection region, this is a "two".) -test (Enter the letter only!)
