Frito-lay fills bags of tortilla chips that are labeled with a net weight of 288.5 grams. a random sample of 24 bags is selected and found to have an average net weight of 289.7 grams and a sample standard deviation of 5.6 grams. use a 95% confidence interval to investigate whether the filling process is working properly.

It will reject the null hypothesis.

Step-by-step explanation:

Since we have given that

Hypothesis:

n = 24

Average mean = 289.7 grams

Standard deviation = 5.6 grams

We need to find the 95% confidence interval.

Since n = 24 <30 , so we will use t test.

Now, degrees of freedom = n- 1 = 24-1 =23

So,

Since t(calculated)>t

1.05>0.685

So, it will reject the null hypothesis.

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
