Question

Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 582 randomly selected adults showed that 64​% of them would erase all of their personal information online if they could. Find the value of the test statistic. The value of the test statistic is nothing. ​(Round to two decimal places as​ needed.)

Answer 1

Answer:

6.76

Step-by-step explanation:

Let us create hypothesies as

$H_0: p =0.50\\H_a: p>0.50$

(right tailed test for claiming most adults would erase)

Sample proportion p = 0.64

n = sample size = 582

Std error of proportion= $\sqrt{\frac{0.5*0.5}{582} } \\=0.0207$

P difference = 0.14

Test statistic = p difference/std error

= 6.755

=6.76
