Suppose students' ages follow a skewed right distribution with a mean of 24 years old and a standard deviation of 3 years. if we randomly sample 350 students, which of the following statements about the sampling distribution of the sample mean age is incorrect?
a. the shape of the sampling distribution is approximately normal.
b. the mean of the sampling distribution is approximately 24-years old.
c. the standard deviation of the sampling distribution is equal to 5 years.
d. all of the above statements are correct.

Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Mean of students' age = 24 years

Standard deviation of students' age = 3 years

Sample size = number of students = 350

So, according to options,

a. The shape of the sampling distribution is approximately normal.

It is true as n >30, we will use normal.

b. The mean of the sampling distribution is approximately 24-years old.

It is true as it is given.

c. The standard deviation of the sampling distribution is equal to 5 years.

It is not true as it is given 3 years.

Hence, Option 'c' is correct.

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
