The following 3 questions will be about the following hypothesis test (the prompt will be repeated in each of the 4 questions to make things easier):   A city mayor claims that more than 60% of residents support building a new public park. A random sample of 250 residents found that 158 support the new park. Use a 5% level of significance to test the mayor’s claim.

A manufacturing manager believes the mean lifespan of a certain type of light bulb is not 1,200 hours. A random sample of 40 light bulbs showed a mean lifespan of 1,165 hours with a standard deviation of 85 hours. Use a 0.05 level of significance to test the manager’s claim. (Round to 3 decimal places as needed)   a. What type of test is this? (left-tailed, right-tailed, or two-tailed) [a] b. p-value = [e] c. The p-value is [b] (less than/greater than) alpha, so we [c] (reject/fail to reject) the null hypothesis. There [d] (is/is not) enough evidence to conclude that the population mean lifespan of a certain type of light bulb is not 1,200 hours.
