Answer:
C. Correct
Step-by-step explanation:
The interpretation of a confidence interval of x% is that we are x% that this interval contains the mean of the population.
So, for example, the interpretation of a confidence interval of 95% is that we are 95% that this interval contains the mean of the population.
In this problem, we have that:
Based on the results, a 95% confidence interval for mean number of hours worked was lower bound: 41.5 and upper bound: 45.6.
Also, the following affiration:
(A) There is a 95% chance the mean number of hours worked by adults in this country in the previous week was between 41.5 hours and 45.6 hours.
This is correct
So, the answer is:
C. Correct
Answer:
wait whats the question-
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>The scale is </u>
- 15 in ÷ 24 feet =
- 15 in ÷ 24*12 in =
- 15 in ÷ 288 in =
- 5 in ÷ 96 in =
- 5 ÷ 96
3 boxes times 40 = 120 + 3 = 143
or 3 boxes times 43 = 129
Answer:
See below
Step-by-step explanation:
From the table we see there is a relation between x and y values
Every step change of x = 0.5, every step change of y = 2
<u>This relation is linear. The formula for linear function is:</u>
<u>Using to pairs of points to get the slope and y-intercept</u>
<u>Calculating the slope:</u>
- m = (64 - 60)/(1 - 0) = 4/1 = 4
- y - intercept is 60 as per point (0, 60)
<u>So the function is</u>
<h3>Part A</h3>
<h3>Part B</h3>
<h3>Part C</h3>
- Slope is the steepness of the line.
- y -intercept is the lowest score with no time spent studying
