Answer: $H_0:\mu=421$

$H_a : \mu\neq421$

Step-by-step explanation:

A null hypothesis is a type of hypothesis that is used in statistics that assumes there is no difference between particular characteristics of a population wheres the alternative hypothesis shows that there is a difference.

Given: A 37 bag sample had a mean of 421 grams.

Let $\mu$ be the population mean.

Then, the null hypothesis would be:

$H_0:\mu=421$

whereas the alternative hypothesis would be:

$H_a : \mu\neq421$

Identify an equation in point-slope form for the line perpendicular to

Alik [6]

Answer:

Step-by-step explanation:

Perpendicular lines have the exact opposite slope of the other equation.

So the slope will be x or 1x. Plug in

-8 = 1(4) + b (b represents y-intercept) like y=mx+b

-8 = 4 + b (subtract 4 on both sides)

-12 = b

The equation is y = x - 12

solve

y + 8 = x - 4 (subtract 8 on both sides)

y = x - 12
