In a random sample of 9 cell phones, the mean full retail price was $546.70 and the standard deviation was $195.00. further research suggests that the population mean is $428.87. does the t-value for the original sample fall between minus−t 0.99 and st 0.99?

Step-by-step explanation:

We are given the following in the question:  

Population mean, μ = $428.87

Sample mean, = $546.70

Sample size, n = 9

Sample standard deviation, s = $195.00

Formula:

Putting all the values, we have

Thus, the t-value does not lie in the interval (-0.99,0.99)

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
