Which of the following statements applies to a point estimate? the point estimate will tend to be accurate if the sample size exceeds 30 for non-normal populations. the point estimate is needed to determine the required sample size when estimating the population mean. the point estimate is a parameter. the point estimate is subject to sampling error and will almost always be different from the population value.

the correct answer is d

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
