Answer:
PLEASE HELP!!!
1. Under what conditions must we assume a Student t distribution for the sampling distribution of sample means when testing a claim about a population mean?
2. Give one difference between the Student t distribution and the normal distribution.
3. Which TI-84 calculator command or StatCrunch dialog box is used to find the P-value given a t test statistic?

Answer:
Below.
Step-by-step explanation:
To find the answer, you have to compare the two equations:
and 
So first, the graph looks different because the two slopes are different. The first one will be more vertical than the second one.
The second difference is the y - intercepts. The first equation starts at (0, 60) and the second starts at the origin.
Solve by elimination:
S = shirt
T= tie
3s+5t=60
2s+3t=39
=
Shirt = 15
Tie = 3
