Answer:
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:

If he does not earn any income, he receives $225 from each program. For each dollar he earns (which his employer is required to report to the welfare agency), his benefit from each program is reduced by 75 cents until the benefit equals zero.

Answer:
$73.58
Explanation:
Total cost of product = $120
Total cost of product = Cost of material + Direct labor + Overhead
Cost of material = (3 * direct labor) - $6
Overhead = ¾ of Direct labor
Total cost of product = 3DL - $6 + DL + ¾ of DL
$120 = 3DL - $6 + DL + 0.75 DL
$126 = 4.75 DL
Direct Labor = 126/4.75
Direct Labor = $26.53
Material cost = 3 * $26.53 - $6
Material cost = $73.58
