Answer:
Given:
Mean, u = 2100
A golf magazine reports the mean gain to be $2100, while the teaching professional believes the average gain is not $2100.
Here the null and alternative hypotheses would be:
Null hypothesis:
H0: u = 2100
Alternative hypothesis:
Ha: u ≠ 2100
b) Here, given the level of significance,
as 0.10. This means that:
The probability that the null hypothesis H0 is rejected when average gain is $2100 is 0.10
If 2 inches equals 40 miles, then 1 inch equals 20 miles.
115 miles/20 miles=5.75
The cities would be 5.75 miles apart on the map.
It is given in the problem that
Liam buys a motorcycle for $2,900
Its value depreciates annually at a rate of 12%=0.12
At the end of t years, it has a value of less than $2,000
The exponential equation modeling this situation can be written as below
The inequality representing its value less than $2,000 can be written as below
