A random sample of 101 recorded deaths in the United States during the past year showed an average life span of 71.8 years. Assuming a sample standard deviation of 8.9 years, does this seem to indicate that the population variance is more than 64 squared years? Use a 0.05 level of significance. Answers that use CIs will not be accepted. Formulate and carry out the appropriate hypothesis test using the critical region approach.

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 140 engines and the mean pressure was 5.4 pounds/square inch (psi). Assume the population standard deviation is 1.0. If the valve was designed to produce a mean pressure of 5.6 psi, is there sufficient evidence at the 0.01 level that the valve performs below the specifications? Step 5 of 6: Identify the level of significance for the hypothesis test.
A factory that manufactures screws is performing a quality control experiment. Each object should have a length of no more than 13 centimeters. The factory believes that the length of the screws exceeds this value and measures the length of 70 screws. The sample mean screw length was 13.01 centimeters. The population standard deviation is known to be σ=0.15 centimeters. What is the null hypothesis? What is the alternative hypothesis?
Can we use the standard deviation to compare variability of two or more datasets? Is the z-score a real measure of dispersion? If the data is highly skewed, can we still rely on the kurtosis coefficient?
The mean annual temperature of a place is reported in literature to be 16.5°C. Measurements over 1992 to 2009 show a mean temperature of 14.65°C and a variance of 4.75°C. Test the hypothesis that the mean annual temperature of the place has changed from the past at a significance level of 5%.
You may need to use the appropriate appendix table or technology to answer this question. A magazine conducts an annual survey with higher values indicating better service. A sample of 34 ships that carry fewer than 500 passengers resulted in an average rating of 85.33, and a sample of 44 ships that carry 500 or more passengers provided an average rating of 81.80. Assume that the population standard deviation is 4.55 for ships that carry fewer than 500 passengers and 3.97 for ships that carry 500 or which readers rate their favorite cruise ship. All ships are rated on a 100-point scale, more passengers. (a) What is the point estimate of the difference between the population mean rating for ships that carry fewer than 500 passengers and the population mean rating for ships that carry 500 or more passengers? (Use smaller cruise ships - larger cruise ships.) (b) At 95% confidence, what is the margin of error? (Round your answer to two decimal places.) (c) What is a 95% confidence interval…
A researcher wonders whether the recession has changed variability in family size in his city. Before the recession, the mean was 3.7 and the standard deviation was 1.76. The researcher randomly selects 41 families from a population that is normally distributed. His sample has a mean of 3.1 and a standard deviation of 1.45. Test the claim that the standard deviation in size has changed at the αα=.05 significance level.
The amount of water consumed each week by Bronx residences is normally distributed. The population mean of water consumption is 120.3 gallons with a standard deviation of 10.0 gallons. Test the claim at the 0.10 significance level that the average amount of water consumed is not 125 gallons with a sample size of 100 residences. Do you retain or reject the null hypothesis?
Suppose the mean weight of King Penguins found in an Antarctic colony last year was 15.4 kg. In a sample of 35 penguins same time this year in the same colony, the mean penguin weight is 14.6 kg. Assume the population standard deviation is 2.5 kg. At .05 significance level, can we reject the null hypothesis that the mean penguin weight does not differ from last year? Use P-value approach.
have a standard deviation of 2.40 and a variance of 5.78 is this considered high or low and will the distribution be peaked or Platykurtic?
The mean length of steel bolts from a manufacturing process is advertised as 15.1 mm. An inspector believes that this value is not correct. To investigate the inspector's claim, the lengths of a random sample of size 280 bolts are measured and found to have a sample mean of 15.6 mm. We will assume that the population of bolt lengths is normally distributed with standard deviation of 5.0 mm. Test whether the mean population length has changed at a level of significance of 10%. Show your relevant steps below. Step 1: Hypotheses: • The null hypothesis Ho is (choose one): = 5.0 u = u = 15.1 OH = 15.6 u = 280.0 • For the alternative hypothesis H. we change the equal sign in Ho to (choose one): Step 2: Rejection Region: The rejection region is bounded by the following critical values: Critical z value(s) =
Using traditional methods, it takes 11.7 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 23 students and observed that they had a mean of 11.3 hours with a standard deviation of 1.4 A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Assume the population distribution is approximately normal. Make the decision to reject or fail to reject the null hypothesis. Is it reject null hypothesis or fail to reject null hypothesis
