Answer:
Probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.
Step-by-step explanation:
We are given that the diameters of ball bearings are distributed normally. The mean diameter is 106 millimeters and the standard deviation is 4 millimeters.
<em>Firstly, Let X = diameters of ball bearings</em>
The z score probability distribution for is given by;
Z = 
~ N(0,1)
where, 
= mean diameter = 106 millimeters
= standard deviation = 4 millimeter
Probability that the diameter of a selected bearing is greater than 111 millimeters is given by = P(X > 111 millimeters)
P(X > 111) = P( > 
) = P(Z > 1.25) = 1 - P(Z 
1.25)
= 1 - 0.89435 = 0.1056
Therefore, probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.
The estimated number of students at the M College who agree climate change is a serious issue is 1759
The percentage of total students is 59.42%
The method used can be biased.
<h3>How many students believe climate change is a serious issue?</h3>
The students surveyed are the sample while the students in the M College are the population. A population is the party of interest in an experiment. A population consists of all the members of the group. A sample is a smaller group of the population.
The limitation of using a sample to estimate for the population is that the sample might be a biased estimate of the population. If the sample is biased, the result of the experiment would be inaccurate.
Estimated number of students at M College = (sample that agree that climate change is a serious problem / total number of people surveyed) x number of students
(205 / 345) x 2960 = 1759
Percentage = (1759 / 2960) x 100 = 59.42%

The absolute value lines basically just serve as parentheses in this equation.
(2-1)/(2-1) = 1
(1)/(1) = 1
