Answer:
Mean of the Population or The claimed population mean 'μ' = 5.5 hrs.
Mean of the sample 'x⁻' = 6.25 hours
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data A recent article in a college newspaper stated that college students get an average of 5.5 hrs. of sleep each night
Discuss about total college students so
<em>Mean of the Population 'μ' = 5.5 hrs.</em>
Given random sample size 'n =25
Given data the sampled students slept 6.25 hours per night
<em>mean of the sample 'x⁻' = 6.25 hours</em>
Mode is the number that occurs the most
1 is the mode
the range is the maximum minus the minimum
8-1
7 is the range
8n ≥425-175
8n ≥250
n ≥250/8
n ≥31.25
They would need to sell at least 32 bottles to raise more or equal to $425.
32•8=256
256+175=$431
431 ≥425
