" select all statements that correctly evaluate the report.
a the sample is biased because it does not represent the population.
b. the question is biased toward a no response.
c. the sample is not biased.
d. the question is not biased.
e. the question is biased toward a yes response.

A and E are correct.

Step-by-step explanation:

The correct statements are :

A. The sample is biased because it does not represent the population.

E. The question is biased toward a Yes response.

Explanation for A:

This is a biased sample as all the members were not included in the study. Only first 50 people were asked out of possible hundreds of people who go to the library. So, this option is true. Only 50 people does not represent a population.

Explanation for E:

It is obvious that the people who are the first to come to the library are very much keen to come early, so they will definitely say yes to the question. So, the option holds true to the fact that question is biased towards a yes response.

answer: 20

step-by-step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
