The velocities (in feet/min) of currents in the Columbia River in Washington State were measured every minute for just over an hour at a depth 95% the depth of the river. The velocities are listed in the table below. 210 208 197 194 210 221 199 210 210 205 201 194 214 163 201 203 208 190 210 217 217 201 184 188 172 184 214 199 205 210 210 201 221 205 192 212 208 226 181 197 212 201 212 194 203 181 202 188 218 201 197 208 197 199 201 199 199 190 205 197 201 236 194 214 210 194 Use this information to answer the following problems.
NarStor, a computer disk drive manufacturer, claims that the average time to failure for its hard drives is 14,400 hours. You work for a consumer group that has decided to examine this claim. Technicians ran 16 drives continuously for three years. Recently the last drive failed. The time to failure (in hours) are given below. Time Until Failure(Hours) 330 620 1870 2410 4620 6396 7822 8102 8309 12,882 14,419 16,092 18,384 20,916 23,812 25,814 Conduct a hypothesis test to determine whether there is any evidence that the average time to failure is less than the manufacturer’s claim. Use alpha = 0.01 What assumption did you make in performing the test? What is the p-value?
A tank is leaking at an increasing rate as indicated by the data below. Use the table to answer the following questions. Time (hr) Leakage (gal/hr) 1 30 2 3 7 8 720 4 65 150 240 290 410 550 650 An upper limit estimate for the amount of material leaked after 4 hours is (Simplify your answer.) gal. A lower limit estimate for the amount of material leaked after 4 hours is gal. (Simplify your answer.) An upper limit estimate for the amount of material leaked after 8 hours is (Simplify your answer.) gal. A lower limit estimate for the amount of material leaked after 8 hours is gal. (Simplify your answer.) If the leakage occurs at a constant rate of 720 gal/hr after 8 hours and the tank initially held 20,000 gallons of material, an estimate for the least amount of time for the tank to empty is hr. (Round to the nearest tenth as needed.) If the leakage occurs at a constant rate of 720 gal/hr after 8 hours and the tank initially held 20,000 gallons of material, an estimate for the most amount…
Can balloons hold more air or more water before bursting? A student purchased a large bag of 12-inch balloons. He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here are the data
