Simple random sample from a population with a normal distribution of 99 body temperatures has x overbarequals98.20degrees upper f and sequals0.63degrees upper f. construct a 95% confidence interval estimate of the standard deviation of body temperature of all healthy humans. is it safe to conclude that the population standard deviation is less than 1.50degrees upper f?

Step-by-step explanation:

Let x be the normal body temperature

X is N(99, sigma)

Sample mean x bar = 98.2 and s = 0.63

Margin of error = Z critical * 0.63 = 1.95 *0.63 = 1.2285

It is safe since 1.5 <1.96 critical value of z at 95%

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
