Question

z= phat-p divided by the square root of pq divided by n. how do you put that correctly into the calculator

Answer 1

That depends, your wording is ambiguous.

As is, what you wrote can be read as one of any of the following (not all the possibilities, either):
\[z=\frac{\hat{p}-p}{\left(\dfrac{\sqrt{pq}}{n}\right)}\]
\[z=\frac{\left(\dfrac{\hat{p}-p}{\sqrt{pq}}\right)}{n}\]
\[z=\frac{\hat{p}-p}{\sqrt{\dfrac{pq}{n}}}\]
\[\vdots\]
Please clarify.

Answer 2

it is the proportions formula z= p-ha - p / square root of pq/ n

Answer 3

Use some parentheses to group terms. I still have no idea what you mean.

Answer 4

the test statistics formula when finding the hypothesis

Answer 5

example; in a study of 11,000 car crashes it was found that 5588 of them occurred 5 miles from home use a 0.01 significance level to test the claim that more than 50% of car crashes occur within 5 miles of the home

Answer 6

its the last example that you have on there

Answer 7

this is my first time on here i know how to set it up but when i put it in my calculator i never got the right answer
