Answer:
Mean 160
Standard deviation 2.63
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation 
In this problem, we have that:

Find the mean and standard deviation of the sampling distribution of sample means with sample size n = 58.
Mean 160

Answer: 28
Step-by-step explanation:
Number of cases= 33
Percentage increase= 14.6%
To get the number of cases the previous year, we find the increase from last year and subtract.
= 14.6% of 33
= 14.6/100 × 33
= 4.82
So, the increase was 4.82
To get last year number, we subtract 4.82 from 33.
33 - 4.82 = 28.18 which is approximately 28.
