Question

Carbohydrates in Fast Foods The number of carbohydrates found in a random sample of fast-food entrees is listed below. Is there sufficient evidence to conclude that the variance differs from 100? Use the 0.05 level of significance. Assume the variables are approximately normally distributed. 44 51 47 38 43 39 53 40 62 46 73 61 63 53 39 52 30 41 38 (c)Compute the test value. Round the answer to three decimal places. =χ2

Step 1

First, we need to find the sample mean (x̄) and the sample variance (s^2) of the given data. The data is: 44, 51, 47, 38, 43, 39, 53, 40, 62, 46, 73, 61, 63, 53, 39, 52, 30, 41, 38 To find the sample mean (x̄), we add up all the values and divide by the number Show more…
