- if a hypothesis is not rejected at the 0.10 significance level, it A. Must be rejected at the 0.05 level. B. May be rejected at the 0.05 level. C. Will not be rejected at the 0.05 level. D. Must be rejected at the 0.01 level.If a null hypothesis is not rejected at the 0.10 level of significance, it 1 must be rejected at the 0.05 level of significance. 2 might be rejected at the 0.05 level of significance. 3 will not be rejected at the 0.05 level of significance. 4 must be rejected at the 0.01 level of significance.If a null hypothesis is rejected at the 0.05 level of significance, it must be rejected at the 0.01 level. True or False?
- 8) If we have a sample of size 100 from a population of rope with sample mean breaking strength of 960 pounds with standard deviation 200 pounds and we wish to run a hypothesis test with this data to see if the population mean breaking strength differs from 1000 pounds, then what is the TYPE I ERROR? (a) The population mean breaking strength is actually less than 1000 pounds, but our data leads us to us to conclude it is at least 1000 pounds. (b)The population mean breaking strength is equal to 960 pounds, but our data leads us to us to conclude it is not equal to 960 pounds. (c)The population mean breaking strength is at least 960 pounds but our data leads us to conclude it is less than 960 pounds. (d)NONE OF THE OTHERS (e)The population mean breaking strength is not equal to 1000 pounds, but our data leads us to us to conclude it is equal to 1000 pounds.#2.9 Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2026 passenger cars in a particular region, 218 had only rear license plates. Among 346 commercial trucks, 50 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars. Use a 0.05 significance level to test that hypothesis.Test the claim using a hypothesis test. Identify the null and alternative hypotheses for this test. Let population 1 correspond to the passenger cars and population 2 correspond to the commercial trucks. Let a success be a vehicle that only has a rear license plate. Identify the test statistic. State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim.Suppose the significance level of a certain hypothesis test is α = 2.5% and the p-value is equal to 0.0255.What is the correct conclusion?
