Suppose the null hypothesis, Ho, is: the mean age of the horses on a ranch is 6 years. What is the Type lI error in thisscenario?Select the correct answer below:OOOOYou think the mean age of the horses on a ranch is 6 years when, in fact, it is.You think the mean age of the horses on a ranch is 6 years when, in fact, it is not.You think the mean age of the horses is not 6 years when, in fact, it is.You think the mean age of the horses is not 6 years when, in fact, it is not.

given null hypothesis is mean age of horses on a ranch is 6 years. Type-II error is when we fail to…

. Suppose a researcher has heard that children watch an average of ten hours of TV per day. The researcher believes this is wrong but has no theory about whether it's an overestimate or an underestimate of the truth. If the researcher wants to do a z-test of one population mean, what will the researcher's alternative hypothesis be?
Suppose you are asked to conduct a two-tailed hypothesis test on the population mean. What type of hypothesis test would you use? Why? What assumptions do you need to make about the process when you are conducting a hypothesis test on the population mean in order for your results to be valid?

Classify the hypothesis test as two-tailed, lefttailed, or right-tailed. A manufacturer claims that the mean amount of juice in its 16 ounce bottles is 16.1 ounces.

When a person states at the outset of an experiment that a higher average score will be received by a group receiving some kind of treatment when it is compared to the mean of a group that did not receive the treatment, the need for a _________________ is apparent. a. one-tailed test b. two-tailed test c. an independent groups test d. a matched groups test
A personality test has a subsection designed to assess the "honesty" of the test-taker. Suppose that you're interested in the mean score, 4, on this subsection among the general population. You decide that you'll use the mean of a random sample of scores on this subsection to estimate L. What is the minimum sample size needed in order for you to be 90% confident that your estimate is within 5 of u? Use the value 21 for the population standard deviation of scores on this subsection. Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements). (If necessary, consult a list of formulas.) ?
A teacher collects the following data from 5 college students regarding the number of times they drank alcohol in the last 30 days. We know that the population of college students drink a mean of 4.0 days in the last 30 days (i.e., this is the population mean). Is the mean level in the sample significantly different from the population mean? data: 6,5, 7, 6, 4 - what type of error might you be making - interpret effect size
