Students of a large university spend an average of $5 a day on lunch. The standard deviation of the expenditure is $3. A simple random sample of 36 students is taken. a) What is the expected value, standard deviation, and shape of the sampling distribution of the sample mean

Answer and Step-by-step explanation:

According to the situation the solution is shown below:-

The expected value is

The standard deviation is

= $3

The sample distribution of the sample standard deviation is

After solving the above equation  we will get

= 0.5

Basically we applied the applied formula so that each part could be determined

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
