Answer:
95% Confidence interval = (23.4,26.2)
Step-by-step explanation:
In this problem we have to develop a 95% CI for the mean.
The sample size is n=49, the mean of the sample is M=24.8 and the standard deviation of the population is σ=5.
We know that for a 95% CI, the z-value is 1.96.
The CI is

</span><span>Now we can observe the numerical value of 4,900 as the rounding number which becomes
4900 = 5000
4800 = 5000
4700 = 5000
4600 = 5000
4500 = 5000
