b) To estimate the mean salary of professors at her university, Patricia collects data by recording the salaries of all professors included in 12 randomly selected departments.
c) Elizabeth wants to estimate the mean height of students at her school. She collects data by selecting a random group of students within her classroom.
d) To estimate the mean grade point average of students at her school, Annie collects data by recording the grade point average of every 25th student on the list of students after randomly selecting first student.
Answer:
(C) Elizabeth wants to estimate the mean height of students at her school. She collects data by selecting a random group of students within her classroom.
Step-by-step explanation:
In option C, the sample is an example of convenience sampling, It is not representative of the population of student being studied.
Convenience sampling is a type of non-probability sampling method in which the sample is taken from the part of the population easy to reach.
The sample are not chosen at random thereby undermining the ability to generalize the results from the sample to the entire population under study.

Answer:I spent more time at the farm because I got there before Jordan got there.
Step-by-step explanation:
y= 1/5 x + 4
Answer:
The slope is and the y-intercept is .
Step-by-step explanation:
We are given an equation in slope-intercept form (y = mx + b).
In this equation, we can define the following variables:
The slope in an equation and of a line is the rise over run of a line. The numerator of the fraction will be how many y-coordinates the line will ascend or descend (depending on the sign). The denominator will signify how many x-coordinates the line will move to the left or the right.
The y-intercept is the coordinate at which the line crosses the y-axis. The value of x is 0 and the coordinate can be positive or negative.
Therefore, by looking at our equation, we can see that is the slope, and 4 is the y-intercept.

how to find ?
Divide your confidence level by 2: . 95/2 = 0.475. Step 2: Look up the value you calculated in Step 1 in the z-table and find the corresponding z-value. The z-value that has an area of .
