- The manager of a milk store wants to know if the milk in the 1-gallon cartons actually averages 1-gallon. State null and alternative hypotheses.If a police officer wants to find out whether the average speed of motorists on a highway with a speed limit of 55 mph is greater than 55 mph, then the null hypothesis is 55. false trueThere was a claim that an average of 370 000 vehicles pass through EDSA every day. A statistician wants to test this claim and check if the average is really 370 000 or not. (State the null and alternative hypotheses in words and in symbols)
- A manufacturer claims that the batteries for a laptop can last up to 6 hours from full charge. State the null and alternative hypotheses and identify the claim of the manufacturer.A student pursuing a degree in English as a second language believes the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak English. To test her claim she randomly selects 373 female factory workers and out of them 43 could not speak English. She then randomly selects 215 male factory workers and out of them 65 could not speak English. Test her claim at .=0.05 to see if she was right. The correct hypotheses are: H : PF Pu (claim) H : PF 2 PM HA: PF < Pr (claim) H : PF = PM HA: PF + PM (claim) Since the level of signficance s0.05 the critical value is-1.64s The test statistic is pound to 3 places) The pvalue is round to 3 places) The decision can be made to oreject H, odo not reject í, The final conclusion is that: There is enough evidence to reject the claim that the proportion female factory workers who can't speak English is less than the proportion of male factory workers who can't speak English. There is…A study conducted to see if teenagers drive at faster average speeds than the general population of drivers. The average speed of the driving population is 45mph. The null hypothesis is Ho=uaverage driving speed of teenagers = 45 mph. What is the alternative hypothesis?
- A company wants to test if the average amount in the 12oz cans that they produce is less than it should be. Write the null and alternative hypothesis.A nationwide survey claimed that at least 55% of parents with young children condone spanking their child as a regular form of punishment. In a random sample of 100 parents with young children, how many would need to say that they condone spanking as a form of punishment in order to refute the claim at a=0.5 a.You would need exactly 46 parents to support spanking to refute the claim. b.You would need more than 46 parents to support spanking to refute the claim. c.You would need 46 or less parents to support spanking to refute the claim. d.You would need 47 or less parents to support spanking to refute the claim.It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet. A transportation researcher wants conduct a hypothesis test to determine if the stopping distance is less than 120. What is Type II error in the context of this problem?
- A meteorologist stated that the average temperature during July in Chattanooga was 80 degrees. A sample of July temperatures over a 32-year period was taken. The correct set of hypotheses isA medical journal published new medical research about diastolic blood pressure. Let the mean diastolic blood pressure reading be u mmHg. If a doctor wants to know if the new medical research discussed in the journal results in diastolic blood pressure readings that are, on average, less than 75 mmHg, what are the null and alternative hypotheses? Select the correct answer below: Ho: µ = 75; Ha:H 75 %3D O Ho: µ = 75; Ha: µ + 75A taxi company manager is trying to decide whether to use radial tires instead of regular belted tires improves fuel economy. Twelve cars were equipped with radial tires and driven over a prescribed test course. Without changing drivers, the same cars were equipped with regular belted tires and driven once again over the course. The gasoline consumption, in kilometers per liter, was recorded as follows: (See photo) Can we conclude that cars equipped with radial tires gives better fuel economy than those equipped with belted tires. Assume the populations to be normally distributed. Use a 0.05 level of significance.
