How would I solve this problem. A researcher wishes to estimate the mean height of women aged between 60 and 65 in the U. S. She desires a margin of error of 0.3 inches. Past studies suggest that a population standard deviation of 3.3 inches is reasonable. Estimate the minimum sample size needed to estimate the population mean with the stated accuracy.

465

Step-by-step explanation:

Margin of error = critical value × standard error

ME = CV × SE

Assuming 95% confidence, CV = z = 1.96.

Standard error is:

SE = σ / √n

SE = 3.3 / √n

Given margin of error of 0.3:

0.3 = 1.96 × 3.3 / √n

n = 465

0.32

step-by-step explanation:

2.24/7

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
