Aconsumer group claims that the mean acceleration time from 0 to 60 miles per hour for a sedan is 7.9 seconds. a random sample of 33 sedans has a mean acceleration time from 0 to 60 miles per hour of 7.6 seconds. assume the population standard deviation is 2.3 seconds. find the standardized test statistic and the corresponding p-value.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

2y+y=5

add 2y and y

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00
