115.3 hertz
Step-by-step explanation:
For either interval, the value of the sample mean is given by the average of the lower and upper bound of the confidence interval. Since both intervals were constructed by using the same sample, both values should be equal.
For the first interval:

For the second interval:

It would be associative property because the order of the numbers stayed the same
the answer would be the third choice which is N(0, z)
You need to go from slope-intercept (

) to standard form (

).
slope-intercept form of your provided values:
now, solve for x and y
Your answer is 
.
