A sheet metal firm intends to run quality control tests on the shear strength of spot welds. As a guideline for choosing a sample size, they decide to take the smallest number of observations for which there is at least a 95% chance that the ratio of the sample variance to the true variance will be less than 2. Find the minimum n.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
