Explanation:
Data given and notation
represent the sample mean
represent the standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to determine if the mean is lower than 5600, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We don't know the population deviation, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:
Answer:
b. $433,750
Explanation:
The ending balance in retained earnings can be calculated as;
= Beginning balance + Net income - Cash dividends
Given that;
Beginning balance = $430,000
Net income = $60,000
Cash dividends = $56,250
= $430,000 + $60,000 - $56,250
= $433,750
Therefore, the ending balance in retained earnings is $433,750
