U n velow, or select another question 04(0/1) te: 1/4 Given the following sampling distribution of one mean with a sample size 64, from a normally distributed population, find the population standard deviation, Version 85 86

Answer 1

Using normal curve,

$\sigma$$\bar{x}$ = (87 - 1) = 1  

Now,

$\sigma$$\bar{x}$ = $\sigma$ / sqrt(n)

$\sigma$ = $\sigma$ $\bar{x}$ * sqrt [ n]  

= 1 * 8

= 8
