Question

According to the National Center for Education Statistics, 20% of students who recently earned bachelor’s degrees were business majors. Imagine taking an SRS of 300 students who recently earned bachelor’s degrees and calculating = the proportion of students in the sample who majored in business.

(a) Identify the mean of the sampling distribution of ______. (Response area) Why can we find the mean? ____(Response area)

(b) Calculate and interpret the standard deviation of the sampling distribution of . ____ (Response area) Why can we find the standard deviation? _____(Response area)

choices:

60 students

0.20 students

0.0231 students

48 students

6.93 students

We can always find this

The sample size is large

np and n(1 - p) are both at least 10

The 10% condition is met

Skewed

Approximately Normal

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
