A survey of 1,562 randomly selected adults showed that 522 of them have heard of a new electronic reader. The accompanying technology display results from a test of the claim that 35% of adults have heard of the new electronic reader. Use the normal distribution as an approximation to the binomial distribution, and assume a 0.05 significance level to complete parts (a) through (e). Is the test two-tailed, left-tailed, or right-tailed? Left-tailed test Two-tailed test Right tailed test What is the test statistic? (Round to two décimal places as needed.) What is the P-vahie?

a) We want to test the claim that 35% of adults have heard of the new electronic reader, then the system of hypothesis are.:  

Null hypothesis:  

Alternative hypothesis:  

And is a two tailed test

b)  

c)  

d) Null hypothesis:  

e) Fail to reject the null hypothesis because the P-value is greater than the significance level, alpha.

Step-by-step explanation:

Information provided

n=1562 represent the random sample selected

X=522 represent the people who have heard of a new electronic reader

estimated proportion of people who have heard of a new electronic reader

is the value to verify

represent the significance level

z would represent the statistic

represent the p value

Part a

We want to test the claim that 35% of adults have heard of the new electronic reader, then the system of hypothesis are.:  

Null hypothesis:  

Alternative hypothesis:  

And is a two tailed test

Part b

The statistic for this case is given :

(1)  

Replacing the info given we got:

Part c

We can calculate the p value using the laternative hypothesis with the following probability:

Part d

The null hypothesis for this case would be:

Null hypothesis:  

Part e

The best conclusion for this case would be:

Fail to reject the null hypothesis because the P-value is greater than the significance level, alpha.

a² + b²= c²

24² + 7² = c²

c= 25

1/4 because there is 4 grades.
