Do I answer these all or just one?
Step-by-step explanation:
Answer: e. test for a difference in two population means
Step-by-step explanation:
Since the researcher takes a random sample of patients and measures their cholesterol levels before and after a treatment cycle of the drug, then the two samples are matched pairs. The difference between both samples would be determined and the mean and standard deviation of this difference is calculated. This would be used to determine the test statistic.
Therefore, the type of hypothesis test that they should use is
e. test for a difference in two population means
300/150 = 2 days is how long one case will last. 7/2 = 3.5 cases needed to last 7 days. So, you need a total of 4 cases in order to have enough soap.

Step-by-step explanation:
Answer:
105
Step-by-step explanation:
The sum of four exterior angle is always 360 degrees for a quadrilateral
95+ 70+90+b = 360
Combine like terms
255 +b = 360
Subtract 255 from each side
255+b-255 = 360-255
b = 105
