Question
**Survey Analysis and Hypothesis Testing** A survey was conducted with a simple random sample of 1,278 adults. Among these respondents, 68% rated themselves as above average drivers. The aim is to test the claim that \(\frac{3}{5}\) of adults rate themselves as above average drivers. Complete the following parts: **a. Calculation** - Calculate the number of respondents who rated themselves as above average drivers: \[ 0.68 \times 1278 = 869 \] - (Round to the nearest whole number as needed.) **b. Sample Proportion** - Identify the sample proportion and use the symbol that represents it: \[ \hat{p} = 0.68 \] - (Type an integer or a decimal rounded to two decimal places as needed.) **c. Hypothesis Test** - Identify the value used for the population proportion in the hypothesis test and use the symbol that represents it: \[ P = \frac{3}{5} \] - (Type an integer or a decimal rounded to two decimal places as needed.)

Expert Solution
Step 1

The sample size is 1278.

The sample proportion is 0.68.

We have to test the clam that 3/5 of adults rate themselves as above average drivers or not.

This is z-test for population proportion.
