What is the optimal time for a scuba diver to be on the bottom of the ocean? That depends on the depth of the dive. The U.S. Navy has done a lot of research on this topic. The Navy defines the "optimal time to be the time at each depth for the best balance between length of work period and decompression time after surfacing. Let x = depth of dive in meters, and let y = optimal time in hours....

4) A used car dealer says that the mean price of a 2019 Honda CR-V is more than $24,443. You suspect this claim is incorrect and find that a random sample of 14 similar vehicles has a mean price of $25,050 and a standard deviation of $1084. Is there enough evidence to reject the dealer's claim at a = 0.02? Assume the price of used cars is normally distributed. (18 points total) Step 1: Write the hypothesis statements, identify which...

Alocal retailer daims that the mean waiting time is less than 5 minutes. A random sample of 20 waiting times has a mean of 3.5 minutes with a standard deviation of 21 minutes. Ata -0.01, test the retailer's claim. Assume the distribution is normally distributed The test statistic was calculated to be 3.194 and the critical value from the distribution table is 2.539. What decision and conclusion can you make? Reject the wil hypothesis, there is enough evidence to conclude...

A systems analyst tests a new algorithm designed to work faster than the currently-used algorithm. Each algorithm is applied to a group of 47sample problems. The new algorithm completes the sample problems with a mean time of 14.75 hours. The current algorithm completes the sample problems with a mean time of 16.77 hours. Assume the population standard deviation for the new algorithm is 3.956 hours, while the current algorithm has a population standard deviation of 5.135 hours. Conduct a hypothesis...

5. (12 pts) Using traditional methods it takes 98 hours to receive an advanced flying license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 140 students and observed that they an of 97 hours. Assume the population standard deviation is known to be 6. Is there evidence at the 0.1 level that the technique reduces the training time? Step 1. State the null and alternative hypotheses. Answer: Ho: Ha Step...
