Answer: z= -1.636
Step-by-step explanation:
When population standard deviation is known, then the test statistic is given by :-

, where
= sample mean,
= population mean, n=sample size ,
= standard deviation
As per given,

Hence, the e test statistic to see whether the candy bars are smaller than they are supposed to be : z= -1.636

Answer:
The equation would be y = 8x - 38
Step-by-step explanation:
To find the equation of this new line, we first need to identify the slope of the first line. In slope-intercept form, the slope is always the coefficient of x. This makes the slope of the first equation 8. Since parallel lines have the same slope, our new slope will also be 8.
Given that and the point, we can solve for the equation using point-slope form.
y - y1 = m(x - x1)
y - 2 = 8(x - 5)
y - 2 = 8x - 40
y = 8x - 38
