Answer:
For this case the 95% confidence interval is given (63.5 , 74.4) and we want to conclude about the result. For this case we can say that the true mean of heights for male students would be between 63.5 and 74.4. And the best answer would be:
b. The doctor can be 95% confident that the mean height of male students at the college is between 63.5 inches and 74.4 inches.
Step-by-step explanation:
Notation
represent the sample mean for the sample
population mean (variable of interest)
s represent the sample standard deviation
n represent the sample size
Solution to the problem
The confidence interval for the mean is given by the following formula:
(1)
In order to calculate the mean and the sample deviation we can use the following formulas:
(2)
(3)
In order to calculate the critical value 
we need to find first the degrees of freedom, given by:

Answer:
5.1 (Rounded down to 5)
Step-by-step explanation:
What you do first is
16.8 * 24.3
this is 408.24
now you do 408.24 / 80 which is 5.1
Obviously you cant by 0.1 of a roll but you could just round that down to 5, then the little bit that isnt covered you could just buy a smaller roll of carpet or something
Answer:
the desired equation is y = 3x - 5
Step-by-step explanation:
The correct form of this equation is y = mx + b, where m is the slope and b is the y-intercept.
Any line parallel to the given y = 3x + 6 has an equation of exactly the same form except for the y-intercept (b = 6).
We must find an appropriate y-intercept. To do this, substitute 4 for x and 7 for y in y = 3x + C: 7 = 3(4) + C, or 7 = 12 + C, or C = -5.
Then the desired equation is y = 3x - 5
