When using a two sample test of means with equal standard deviations, then T distribution is the best option for it.
Sample test:
Sample test refers a method of reaching a conclusion to reject or support the claims based on sample data.
Given,
Here we need to identify in which of the following are assumptions made when using a two sample test of means with equal standard deviations.
While we looking into the options for this one, then we have identified that, the sampling distribution of the difference of means is a T distribution.
So, the populations have equal but unknown standard deviation's.
Therefore, we "pool" the sample standard deviation.

The number of payments per year is 12
The number of payments is 36 which means that the term lasted for 3 years.
The total interest is $158.15 and the amount financed is $2500.
The interest rate is
158.15/2500 = 6.33%
In nominal month, that is
(1 + r/12)^12 - 1 = 0.0633
Solve for r
Answer:
Here's what I get
Step-by-step explanation:
Let's assume that the sandwiches are circular (because I couldn't find a good rectangular fraction maker.
Toni ate ¾ of a medium sandwich (Figure below).
Mary Jo ate ⁶/₈ of a medium sandwich.
Mary Jo ate the same amount as Toni, because ¾ = ⁶/₈
Becky ate ¾ of a small sandwich and Toni ate ¾ of a medium sandwich.
Becky ate less than Toni, because ¾ of a small amount is less than ¾ of a large amount.
A) 130 is divisible by 2, 5, 10
b) 123 is divisible by 3
c) 555 is divisible by 3, 5
d) 5564 is divisible by 2
