Answer:
The standard deviation of the sampling distribution of the sample mean score for a random sample of 36 students is 1.
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.
In this problem, we have that:
Then, by the Central Limit Theorem:
The standard deviation of the sampling distribution of the sample mean score for a random sample of 36 students is 1.

Answer:
Annual rate of interest will be 132.876 %
Step-by-step explanation:
We have given amount which he has to pay A = $611.03
He does a monthly payment of $26.17
So principle amount P = $26.17
Time = 2.5 years
As payment is done monthly so time period = 12×2.5 = 30 periods
Future amount is given by
%
So annual rate will be 11.07×12 = 132.876%
Annual rate of interest will be 132.876 %
