A local car dealer claims that 25% of all cars in San Francisco are blue. You take a random sample of 600 cars in San Francisco and find that 141 are blue. Conduct a hypothesis test to see if you can reject the dealer's claim with a significance level of 0.05. Include all ten steps of the hypothesis testing process.
Write your answer on a piece of paper and upload a photo or scan, or else type your answer into a electronic document and upload that document.
In order to get full credit you must include all of the following in your
a. Null and alternative hypotheses stated in mathematical terms.
b. The symbol for the test statistic you used to evaluate your hypothesis test.
c. The value of the test statistic you used to evaluate your hypothesis test.
d. The p-value for your test.
e. The statistical result of your test (did you reject or fail to reject?)
f. A sentence explaining the result of your test in business terms rather than mathematical terms (in other words, how would you explain the meaning of this result to someone who has not studied statistics, like your boss?)
