An experiment to investigate the survival time in hours of an electronic component consists of placing the parts in a test cell and running them under elevated temperature conditions. six samples were tested with the following resulting failure times (in hours): 34, 40, 46, 49, 61, 64. (a) calculate the sample mean and sample standard deviation of the failure time. (b) determine the range of the true mean at 95% confidence level.

step-by-step explanation:

is this part of a question or something

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
