Answer:
a) 40 = 8b
b) b = 5
Step-by-step explanation:
(b) 40 = 8 × b
40 ÷ 8 = b
5 = b
Answer:
B
Step-by-step explanation:
half of 59 is 29.5, which is very close to 29. this indicates that this fraction (29/59) is the closest to one half, which is answer choice B.
Multiply 80✖️.065 and you'll get 8.80
Then add it to the total which is 80 +8.80
Which the answer is 88.80
The probability that the selected manager has no college background and only have a fair look is 0.05625
Table is missing. Attached below.
Given,
We have to find the probability that the selected manager has no college background and only have a fair look;
From the table;
The total number of managers surveyed = 160
Number of managers surveyed are fair = 9
Probability;-
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
Here,
The probability = Number of managers surveyed are fair / The total number of managers surveyed
The probability = 9/160 = 0.05625
That is,
The probability that the selected manager has no college background and only have a fair look is 0.05625

The student T distribution would be used since we don't know the population variance (by extension the population standard deviation).
However, if n > 30, then the student T distribution is going to look very similar to the standard normal Z distribution. It won't be a perfect match, but it'll be close enough that it's more simple to use the Z distribution. With the Z distribution, you only have one set of values and you don't have to worry about the degrees of freedom.
