A survey of a random sample of 1,045 young adults found that 60 percent do not have a landline telephone number. Test statistic of the appropriate test?

6.598

Step-by-step explanation:

- A random sample of n = 1,045 young adults found that 60 % do not have a landline telephone number.

- We have to test the hypothesis that whether the data provide statistical evidence that more than 50 percent of all young adults do not have a landline telephone number.

- Let Null Hypothesis,  H_o: p  0.50  

- Alternate Hypothesis, H_1 : p > 0.50  

- The test statistics that will be used here is One-sample proportion test;

               Test = ~ N(0,1)

- Where,  p' = % of young adults who do not have a landline telephone number in a sample of n is = 60%

- Where, n = sample of young adults = 1,045

- So, test statistics =    = 6.598

- Hence, the test statistic for the test is 6.598.
