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
A. They have negative reciprocal slopes
He will have to fly 23 feet, 15 feet down and 8 feet to the acorn
First, Make 2 equations to show each company in which "x" equals the number of days:
Andy's Rental Car = 20 + (30x)
Buddy's Rental Car = 36 + (28x)
Set it up like this:
20 + (30x) = 36 + (28x)
Now, solve for x by simplifying both sides of the equation and then isolating the variable.
x = 8
