12:15 p.m.
385.25 - 29 = 356.25
356.75/75 = 4.75(equivalent to 4 hours 45 minutes)
7:30 + 4:45 = 12:15 p.m.
Answer:
A sample size of 28.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
In this question:
We need to find n for which s = 0.09, with p = 0.66. So
Rounding to the nearest whole number
