In a study of cell phone usage and brain
hemispheric​ dominance, an Internet survey was​ e-mailed
to 6978 subjects randomly selected from an online group
involved with ears. There were 1310 surveys returned. Use
a 0.01 significance level to test the claim that the return rate is
less than​ 20%. Use the​ P-value method and use the
normal distribution as an approximation to the binomial
distribution.

H1​:
p=0.2
C.
H0​:

H1​:
p≠0.2
D.
H0​:
p​ = 0.2
H1​:
p<0.2
E.
H0​:
p>0.2
H1​:
p=0.2

The test statistic is
z=enter your response here.
​(Round to two decimal places as​ needed.)
The​ P-value is
enter your response here.
​(Round to three decimal places as​ needed.)
Because the​ P-value is
▼
less than
greater than
the significance​ level,
▼
fail to reject
reject
the null hypothesis. There is
▼
sufficient
insufficient
evidence to support the claim that the return rate is less
than​ 20%.
