Use the following information to answer the question. A janitor at a large office building believes that his supply of light bulbs has a defect rate that is different thanthe defect rate stated by the manufacturer. The janitor's null hypothesis is that the supply of light bulbs has a defect rate of p - 0.09 (the light bulb manufacturer'sstated defect rate). Suppose we do a hypothesis test with a significance level of 0.01. Symbolically, the null and alternative hypothesis are as follows: Ho: p = 0.09 andHa:p > 0.09.The janitor calculates a p-value for the hypothesis test of approximately 0.113. Choose the correct interpretation for the p-value.O The p-value tells us that the true population rate of defective light buibs is approximately 0.113.O The p-value tells us that the probability of concluding that the defect rate is equal to 0.09, when infact it is greater than 0.09, is approximately 0.113.O The p-value tells us that if the defect rate is 0.113, then the probability that the janitor will have 33 defective light bulbs out of 300 is approximately 0,113. At a significance levelof0.01, this would not be an unusual outcome.O None of these

here given p-value = 0.113 and significance level = 0.01 p-value is probability of getting extreme…

use a hypothesis test to determine if the proportions are statistically different. A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than theproportion of elementary teachers who were single? Use ΅ = 0.01.

University X installed a new water fountain in the gym. The machine is designed to dispense 250 ml of water in a medium sze setting The staff suspects that the machine may be dispensing too much in medium bottles. They decided to take a sample of 50 medium bottles to see if the average amount is significantly greater than 250 ml What are appropriate hypotheses for their significance test? Select one O a HO p 250 ml. Ha p- 250 ml. (Where p is proportion of water dispensed on the setting) O b. HO 250 ml Ha. us 250 ml.
