Answer:
Step-by-step explanation:
Given : Sample size : n= 9
Degree of freedom = df =n-1 =8
Sample mean :
sample standard deviation :
Significance level ;
Since population standard deviation is not given , so we use t- test.
Using t-distribution table , we have
Critical value =
Confidence interval for the population mean :
90% confidence interval for the mean value will be :
Hence, the 90% confidence interval for the mean value=
Answer:
$10408.08>$10400
She will earn more using the daily compounding method.
Step-by-step explanation:
Investment 1 cost $10,000 and earns 4% interest each year.
If interest was paid once a year
Amount = P(1+r)ⁿ
= 10000(1+0.04)
=10000(1.04)
=$10400
If the interest was compounded daily
Amount = P(1+r/n)ⁿᵗ
=10000(1+0.04/365)³⁶⁵
=$10408.08
Since $10408.08>$10400, it means Odette will earn more using the daily method for one year.

Answer:
A. y = 2x - 3
Explaination:
It can't be negative because then the slope would be going downward from left to right, this line is going upwards. Also, the steepness of the slope proves it is a slope of 2 because a slope of 1/2 isn't very steep. You can also count 1 unit over and look how much the line changes to find the slope.
