Asimple random sample of 50 stainless steel metal screws is obtained. the screws have a mean length of 0.73 inches. assume the population standard deviation is 0.012 inches and the confidence level is α = 0.05. find the p-value you would use to test the claim that the screws have a mean length equal to 0.75 inches as indicated on the package label. 0.9999 0.0002 1.9998 0.0001

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b.the means of the data sets are within 3 units from eachother. c.the data sets have the same standard deviation. d.the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.

Which statement accurately explains whether a reflection over the x-axis and a 180° rotation would map figure acb onto itself?

Simply 8x squared + 5(7x squared- x) - 2x =
