Find the value of the statistie they could. A sofware firm survey of 651 randomly selected adults showed that 50% of them would ease all of their personal information online The value of the test statistics (Round to two decimal places as needed)

Answer 1

GIVEN:

Claim: Most adults would erase all of their personal information online if they could.

Sample size of adults

(n) = 651

Sample proportion of adults who would erase all of their personal information online if they could

(p) = 0.59

HYPOTHESIS:

The claim is most adults would erase all of their personal information online if they could. Here we claim "most adults" which indicates more than 50% of adults.

The hypothesis is given by,

(That is, the true proportion of adults who would erase all of their personal information online if they could is less than or equal to 50%)

Ho :p < 0.50

(That is, the true proportion of adults who would erase all of their personal information online if they could is greater than 50%)

H1 :p> 0.50

TEST STATISTIC:

The test statistic is,

z = (Ô-po)/ (po(1 - po))/n

which follows standard normal distribution

CALCULATION:

The test statistic is,

z = (Ô-po)/ (po(1 - po))/n

  

= (0.59-0.50)/(0.50(1 – 0.50))/651

  

= 0.09/0.0196

2=4.59

The test statistic is
2=4.59
