In a small town in Colorado, it was found that 54% of the population support Candidate Randy. In a random sample of 180 residents of this small town, it was found that 85 of them support Randy. Perform a test to determine if less than 54% of the population support Randy. Use a significance level of 0.01%. a. Check all of the requirements that are satisfied. random the distribution is normal since n > 30 the distribution is normal since the distribution is normal the û distribution is normal since np > 10 and ng > 10 b. Identify the null and alternative hypotheses. Enter the parameter as a decimal. Ho: P 0 right-tailed two-tailed O 0.54 H₁: P c. What type of hypothesis test should you conduct (left, right, or two-tailed)? left-tailed 0.54 d. Identify the appropriate significance level. Make sure to enter your answer as a decimal. e. Which calculator function should you use? 1-PropZ Test f. Find the test statistic. Write the result below, and be sure to round your final answer to two decimal places. g. Find the p-value. Enter your answer as a decimal (not a percentage) and round to 4 decimal places.
