Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 464 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 = 6.03

Step-by-step explanation:

The test statistics for a proportion of the population is the z calculated as follows;

Where:

= 0.64

From the rule of large numbers we have, the proportion of adults who will erase their information online will tend towards 1/2 or 0.5 therefore, we have

p = 0.5 as the test

q = 1 - p = 1 - 0.5 = 0.5

n = Sample size = 464

Therefore, z is given by;

=  6.03

The value of the test statistic = 6.03.
