Suppose that on a 100-point test, the teacher's goal is for her students' exam scores to have a standard deviation of at most 8 points. A recent sample of 25 exams has a sample standard deviation of 9.5. Test whether or not her goal was achieved using a 5% level of significance. Calculate the appropriate test statistic (round to 2 decimal places as needed) 33.84

step-by-step explanation:

you get texts and minutes, so why not

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)

both equations and proportions are better.
