Thompson and thompson is a steel bolts manufacturing company. their current steel bolts have a mean diameter of 140140 millimeters, and a standard deviation of 88 millimeters. if a random sample of 4949 steel bolts is selected, what is the probability that the sample mean would be greater than 141.4141.4 millimeters? round your answer to four decimal places.

To solve this, we need to use the z test. The formula for z score is:

z = (x – u) / s

where x is sample value = 141.4 mm and above, u is mean value = 140 mm, s is standard dev = 8 mm.

z = (141.4 – 140) / 8

z = 0.175

From the standard probability tables, the p value at z = 0.175 using right tailed test is:

P = 0.4306

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
