Company A uses a new production method to manufacture aircraft altimeters. A simple random sample of new altimeters resulted in errors listed below.

A political analyst believes that a senator's recent decision to support a bill resulted in a drop of approval ratings. To test this claim, he selects random cities in the state that voted the senator in and compares the approval ratings before the decision to the approval ratings after the decision. If we let d=approval rating after−approval rating before, based on the data below, what are the test statistic and degrees of freedom of an appropriate hypothesis test? Assume that the approval ratings are normally distributed. Round the test statistic to three decimal places.

A production line operation is tested for filling weight accuracy using the following hypotheses. (filling error no more than 6. So, keep the production line running) (filling error greater than 6. So, stop and adjust the production line) The sample size is 64; the sample mean is 6.3; the population standard deviation is 2; and the significance level is 0.01. The probability of making Type II error in this hypothesis test is 0.440. Q1) Which of the following statement correctly describes the Type II error in this hypothesis test is correct? Please select the best answer below. a) We mistakenly conclude that the filling accuracy is acceptable when it is indeed not acceptable. b) We correctly conclude that the filling accuracy is not acceptable. c) We mistakenly conclude that the filling accuracy is not acceptable when it is indeed acceptable. d_ We correctly conclude that the filling accuracy is acceptable. Q2) As the sample size increases, (please see attached screenshot) a)…
The Nero Match Company sells matchboxes that are supposed to have an average of 40 matches per box, with ? = 7. A random sample of 92 matchboxes shows the average number of matches per box to be 42.2. Using a 1% level of significance, can you say that the average number of matches per box is more than 40? (a) Find (or estimate) the P-value. (b) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? (Select below). At the ? = 0.01 level, we reject the null hypothesis and conclude the data are fewer than 40 matches per box. At the ? = 0.01 level, we reject the null hypothesis and conclude that there are more than 40 matches per box. At the ? = 0.01 level, we fail to reject the null hypothesis and conclude that there are fewer than 40 matches per box. At the ? = 0.01 level, we fail to reject the null hypothesis and conclude that there are more than 40 matches per box.

A company had its sales persons undergo training, hoping to improve their sales.Past sales data indicate that the average sale was P4,000 per transaction on anormally distributed population. After training, sales data, taken from a randomsample of 25 salesmen/salesladies, indicates an average sale of P4,500 with astandard deviation of P150. (a) Write the null hypothesis. (b) Write the alternativehypothesis. (c) Formulate and calculate the test-statistic. Is it a one-tail or twotailed test? Did the training work at 95% confidence level? (d) Determine theconfidence interval.

Use the two-proportions z-test to perform the required hypothesis test. Assume that independent simple random samples have been selected from the two populations. A marketing survey involves product recognition in New York and California. Of 558 New Yorkers surveyed, 193 recognized the product while 196 out of 614 Californians recognized the product. At the 5% significance level, do the data provide sufficient evidence to conclude that the recognition rate in New York differs from the recognition rate in California?
