Assuming that the standard deviation of the weights of all members of FSU's Dept of Statistics is 19 lbs, how many members would we need to sample if we wanted to estimate the average weight of the entire dept, and we wanted to be 99% confident that our estimate was within 10 lbs? 05 23 04 24

24

Step-by-step explanation:

We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of .

So it is z with a pvalue of , so

Now, find the margin of error M as such

In which is the standard deviation of the population and n is the size of the sample.

Minimum sample size:

n for which . So

Simplifying by 10

Rounding up, the answer is 24.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

multiply each one by 3.14
