The manufacturer states his research hypothesis as:H: The mean lifetime of the bulbs is greater than 1000 hours.Which of the choices below reflect the correct null hypothesis, and whether the test is one-tailed or two tailed?Select one:a. H.: The mean lifetime of the bulbs is equal to or less than 1000 hours. Test is one-tailed.b. H,: The mean lifetime of the bulbs is less than 1000 hours. Test is one-tailed.c. H,: The mean lifetime of the bulbs is equal to or less than 1000 hours. Test is two-tailed.d. H: The mean lifetime of the bulbs is less than 1000 hours. Test is two-tailed.A canned goods producer wants to test their quality control process for canned pinto beans. Their production standard is that there should be 1.5 cups of beans (fluidsremoved) in a standard #303 can. If the cans have either more beans or fewer beans, the cans are outside the production standard of the company.The quality control analyst constructs the following null hypothesis:H: The cans contain on average 1.5 cups of beans.What is the correct H, and does this call for a one-tailed or a two-tailed test?Select one:a. H.: The cans do not contain 1.5 cups of beans. The test is two-tailed.b. H: The cans do not contain 1.5 cups of beans. The test is one-tailed.c. H.: The cans contain more than 1.5 cups of beans. The test is two-tailed.d. H: The cans contain more than 1.5 cups of beans. The test is one-tailed.The two main methods of statistical inference are Confidence Intervals and Hypothesis Testing.Select one:O TrueO False
