The test statistic of z equals negative 1.37 is obtained when testing the claim that p equals1 divided by 4. a. Using a signific

spin [16.1K]

Answer: a) critical value = 0.0853, b) we reject the null hypothesis.

Step-by-step explanation:

Since we have given that

z = -1.37

And the hypothesis are given below:

$H_0:p=\dfrac{1}{4}=0.25\\\\H_1:p\neq 0.25$

Since α = 0.01

since critical value = 0.0853

As we can see that 0.853 < 0.25.

so, we reject the null hypothesis.

Hence, a) critical value = 0.0853, b) we reject the null hypothesis.

4 Solve for n. 11(n − 1) + 35 = 3n O n = -6 The answer is n=-3

Drupady [299]

Answer:

$\boxed{n=-3}$

You should be correct.

Step-by-step explanation:

$11(n-1) + 35 = 3n\\\\11n-11+35=3n\\\\11n+24=3n\\\\11n+24-24=3n-24\\\\11n=3n-24\\\\11n-3n=3n-3m-24\\\\8n=-24\\\\\frac{8n=-24}{8}\\\\ \boxed{n=-3}$

Hope this helps.
