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:
Answer:
131,250= number of units
Explanation:
Giving the following information:
<u>We need to calculate the number of units to be sold to maintain a profit of $175,000.</u>
Unitary variable cost= $3
Fixed expenses= $350,000
Selling price= $7
Net income= total contribution margin - fixed cost
175,000= number of units*(7 - 3) - 350,000
525,000 = number of units*4
525,000 / 4= number of units
131,250= number of units
NOTE: Your question isn't clear, Johnson. Would you mind checking it and writing it in a way you can be better helped?
Meanwhile, I hope these explanation below helps.
Answer and Explanation:
Two goods are said to be complementary goods if an increase in the price of a particular one leads to a commensurate decrease in the demand that buyers placed for the other one.
A good is said to be a normal good if the reason for an increase in demand is due to an increase in the income of the buyers.
A good is said to be an inferior good if there is a decrease in demand even though the buyers have experienced increase in their income.
