Answer:
Explanation:
For example: Suppose you want to check the average working hour of employees. You may think that the average duration of an employees is 7.6 hours. You want to check this claim so you collect a sample of 20 employees and note their duration of work. (please check attached file for this, and continue)
NULL HYPOTHESIS H0:u= 7.6 HOURS
ALTERNATIVE HYPOTHESIS Ha: ≠7.6 HOURS
alpha=0.05
t= 7.765-7.6/1.25/sqrt(20)
t= 0.165/1.25/4.47
t= 0.165/0.28
t= 0.589
degrees of freedom= n-1=20-1=19
t critical = 2.09
Since t critical is GREATER than t calculated therefore we fail to reject null hypothesis H0.
From this we can conclude that We don't have enough or sufficient evidence to say that the mean working duration is different than 7.6 hours.
The answer is b more than 540 thousand people start a business every year

Explanation:
Mark-up refers to the intended profit margin: It is selling price -cost of production.
For Rockport Fisheries: cost of production is $ 30
Mark -up is 60 %. i.e., profit margin equal to 60 % of cost price
Selling price= cost +mark up
= $30 + (60/100 x100)
=$30+$18
=$48
Answer:
The correct answer is: Service Quality Gap.
Explanation:
The Service Quality Gap refers to the difference between what a company understands a customer's desires and what must be really done to satisfy that consumer. Firms should make all the efforts in their hands to close that breach and provide the customer with the good or service they need to keep their businesses going. When the gap is not closed, the customer's loyalty fails, pushing them to look for different options in other organizations.
