Hi there!
<u><em>Answer:</em></u>
<u><em>t=26</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
First, you subtract by 19 from both sides of an equation.

Then, you subtract by the numbers from left too right.

<u><em>Final answer is t=26</em></u>
I hope this helps you!
Have a nice day! :)

Answer:
a) The test statistic is 
b) The pvalue is 0.0060.
Step-by-step explanation:
Question a:
Ha: pB < pNY
This means that the alternate hypothesis is rewritten as:

While the null hypothesis is:

The test statistic is:

In which X is the sample mean,
is the value tested at the null hypothesis and s is the standard error
pB = 0.581, pNY = 0.832
This means that 
0 is tested at the null hypothesis:
This means that 
Standard error = 0.1
This means that 
Test statistic:



The test statistic is 
Question b:
The pvalue is the probability of finding a proportion less than -0.251, that is, a difference of at least 0.251, which is the pvalue of Z = -2.51.
Looking at the z-table, Z = -2.51 has a pvalue of 0.0060
The pvalue is 0.0060.
