A software firm survey of 595 randomly selected adults showed that 38% of them would erase all of their personal information online if they could. Complete parts (a) and (b) below.
(a) Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information.
(b) Identify the null and alternative hypotheses.

Step-by-step explanation:

a. Let, p be the parameter being tested. From the sample, 38% would erase all of their personal information.

-we know that the value of probabilities are in the range [0,1]:

-Given that 38% is the true value of the claim can be symbolically expressed as p=0.5

b. The null hypothesis usually represents the true value parameter under study.

-As stated above, the true value of the parameter is 38%;

-Hence, the null hypothesis is

#Alternative hypothesis is the control value, given the value of the parameter  p=0.38, the alternative hypothesis is that p has a different value other than 0.39:

14

step-by-step explanation:

14 x 3 = 42
