Answer:
[ 502.5, 517.5]
Step-by-step explanation:
Given:
Mean of the sample, µ = 510
Total sample size, n = 100
Standard deviation = 75
Confidence level = 95%
Now,
The interval for µ is given as:
⇒ µ ±
for 95% confidence level z value = 1.96
Thus,
The interval for µ
⇒ 510 ±
or
⇒ 510 ± 7.5
or
⇒ [ 510 - 7.5, 510 + 7.5 ]
or
⇒ [ 502.5, 517.5]
