Male and female high school students reported how many hours they worked each week in summer jobs. The data is represented in th
e following box plots:
Identify any values of data that might affect the statistical measures of spread and center.
A- The females worked less than the males, and the female median is close to Q1.
B- There is a high data value that causes the data set to be asymmetrical for the males.
C- There are significant outliers at the high ends of both the males and the females.
D- Both graphs have the required quartiles.

Answer:
Step-by-step explanation:
a. Let, p be the parameter being tested. From the sample, 38% would erase all of their personal information.
-we know that the value of probabilities are in the range [0,1]:
-Given that 38% is the true value of the claim can be symbolically expressed as p=0.5
b. The null hypothesis usually represents the true value parameter under study.
-As stated above, the true value of the parameter is 38%;
-Hence, the null hypothesis is
#Alternative hypothesis is the control value, given the value of the parameter p=0.38, the alternative hypothesis is that p has a different value other than 0.39:
