Answer:
98.1, No does not contain, yes contains.
Step-by-step explanation:
Given that
sample size n =103
Sample mean = 98.1
sample std dev s = 0.56
a) the best point estimate of the mean body temperature of all healthy humans = sample mean =98.1
b) 99% confidence interval estimate of the mean body temperature of all healthy humans
We can use Z critical since sample size is large though sigma is not known
99% CI = 
This does not contain 98.6
This sample does not represent the population, i.e. may be biased sample.
c) CI of population mean
= populaiton mean + /- margin of error
=(98.545, 98.656)
Yes contains 98.6
Answer:

Step-by-step explanation:
In order to solve for y, you need to isolate the y in the equation. Thus, to get rid of the
multiplied by the y, multiply both sides by the reciprocal,
. Then, reduce the fraction.

Thus,
.
Y=8x-23
y eqauls eight x minus twenty three
Answer:
x = 1.33 I think.
Step-by-step explanation:
First you would write out your problem
Next you would take away 6 from both sides to get 4 = 3x
Now you would divide both sides by three to get x = 1.33
I think C would equal 15, because 14 + 14 = 28; 15 + 15 = 30 which is greater than 28.
