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?

(4.2*10^-1)*(5.7*10^-1) = (4.2*5.7)*(10^-1 * 10^1)
23.94*10^-2 = .2394
moving the decimal one place to the left is the same thing as dividing by 10 or multiplying by
1/10. 2.394*10^-1, that is the answer you're looking for, B
Answer:
2
Step-by-step explanation:
2x2x2x2 is 8
No, it is not a perfect cube. A perfect cube is a number that is obtained when you cube an integer. For example, 8 (cube of 2), 27 (cube of 3) and 64 (cube of 4). Since -3 cannot be obtained by cubing an integer, it is not a perfect cube.
Answer: 
and 
Step-by-step explanation:
In sampling distribution of 
.
The mean and standard deviation of the sampling distribution of p is given by :-
, where p= population proportion and n= sample size.
Let p be the population proportion of unmarried couples in the United States are mixed racially or ethnically.
As per given , we have
n = 100
p= 14% =0.14
Then, the mean and standard deviation of the sampling distribution of p will be :
Hence, the required answer : and
