What type of variable is "drive an American-made automobile, or not? OA. Discrete B. Qualitative with more than two possible outcomes OC. Continuous D. Qualitative with two possible outcomes What type of hypothesis test is appropriate to conduct for this research? OA. Hypothesis test on a population mean B. Hypothesis test on a population standard deviation C. Hypothesis test on a population proportion Determine the null and alternative hypotheses.

When conducting a hypothesis test, we hope to avoid commiting a type 1 error, which is: 1. Not as bad as committing a type 2 error 2. rejecting a null hypothesis when it is true 3. rejecting the alternate hypothesis when it is true 4. accepting the null hypothesis when the alternate hypothesis is true

If in general a reasearch question needs to be answered by using the null and alternative hypotheses correctly in words and statistical notations? How is it done?

Telephone Calls A researcher knew that before cell phones, a person made on average 2.5 calls per day. He believes that the number of calls made per day today is higher. He selects a random sample of 34 individuals who use a cell phone and asks them to keep track of the number of calls that they made on a certain day. The mean was 2.6. At a=0.01, is there enough evidence to support the researcher's claim? The standard deviation for the population found by a previous study is 0.6. Assume that the variable is normally distributed. Use the critical value method with tables.

A local police chief claims that 46% of all robbery-related arrests are never prosecuted. A sample of 500 arrests shows that 43% of the arrests were not prosecuted. Using this information, one officer wants to test the claim that the number of arrests that are never prosecuted is below what the chief stated. Is there enough evidence at the 0.05 level to support the officer's claim? A)State the null and alternative hypotheses. B) Find the value of the test statistic. Round your answer to two decimal places. C)Specify if the test is one-tailed or two-tailed. D)Determine the P-value of the test statistic. Round your answer to four decimal places. E)Identify the value of the level of significance. F)Make the decision to reject or fail to reject the null hypothesis. G)State the conclusion of the hypothesis test.

-Find the correct null hypothesis and for each correct alternative hypothesis 7. Suppose you hear a claim that the average score on a national exam is 78. You think the average is higher than that, and your sample of 100 students produces an average of 75. What are the null and alternative hypotheses?

Hi please answer

Support for the U.S. death penalty for convicted murderers was 63% in 2014 (Gallup poll results 2018). In a recent survey of 150 randomly selected U.S. adults, 75 said they were in favor of the death penalty for those convicted of murder. Does this sample appear to come from a population with a lower proportion in favor of the death penalty?   a) State the null and alternative hypotheses in words.  b) State the null and alternative hypotheses using symbols.  c) What type of test is this?

1 - find the p-value 2 - reject or fail to reject null hypothesis?

1.) Create a set of hypotheses for a test.
