Arandom sample of 65 bags of white cheddar popcorn weighed, on average, 5.74 ounces with a standard deviation of 0.26 ounce. test the hypothesis that muequals5.8 ounces against the alternative hypothesis, muless than5.8 ounces, at the 0.10 level of significance.

We failed to accept null hypothesis

Step-by-step explanation:

x= 5.74

Standard deviation =

n = 65

We will use z test

Formula :

Substitute the values :

Refer the z table for p value

p value = 0.0314

α = 0.10

p value < α

So, we failed to accept null hypothesis

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
