Answer fast ! the distribution of the values of a population is shown below, and a simple random sample is drawn from the population. based on this information alone, can the sample be used to make inferences about the population?

a. no, because the population values appear to be normally distributed.

b. no, because the population values do not appear to be normally distributed.

c. yes, because the population values appear to be normally distributed.

d. yes, because the population values do not appear to be normally distributed.
(i think it might be "b" but i'm not sure)

C. Yes, because the population values appear to be normally distributed.

Step-by-step explanation:

Given is a graph which shows the distribution of values of a population

The graph has the following characteristics

i) Bell shaped

ii) symmerical about mid vertical line

iii) Unimodal with mode = median =mean

iv) As x deviates more from the mean probability is decreasing and also curve approaches asymptotically the x axis

Hence we find that the curve is a distribution of normal

Option C is right

C. Yes, because the population values appear to be normally distributed.

the answer is 24

step-by-step explanation:

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
