Answer: <u>56.9</u> years to <u>63.1</u> years.
Step-by-step explanation:
Confidence interval for population mean (when population standard deviation is unknown):

, where
= sample mean, n= sample size, s= sample standard deviation,
= Two tailed t-value for
.
Given: n= 24
degree of freedom = n- 1= 23
= 60 years
s= 7.4 years
Two tailed t-critical value for significance level of
and degree of freedom 23:

A 95% confidence interval on the true mean age:

Hence, a 95% confidence interval on the true mean age. : <u>56.9</u> years to <u>63.1</u> years.
Circumference= π*d
circumference= π*10
circumference= 31.42 miles (2.d.p)
Multiply both sides of this fraction by i to cancel out the i in the denominator.
8 * i = 8i
3i * i = 3i^2 = -3
-(8i/3) is the simplified expression.
