If we reject the null hypothesis when testing to see if a certain treatment has an effect, it means the treatment does have an effect. True False
Which of the following types of study support external validity? a. A study using non-randomly selected participants b. A study that adds a new independent variable c. A study that is a direct replication d. A failed replication study B is the answer but why adding new independent variable can support external validity? (please type, no hand-writing)
Based on that information, determine the null and alternative hypotheses. Would this be a one-tailed hypothesis test or a two-tailed test?
A statistics instructor who teaches a lecture section of 160 students wants to determine whether students have more difficulty with one-tailed hypothesis tests or with two-tailed hypothesis tests. On the exam, 80 of the students, chosen at random, get a version of the exam with a 10-point quest that requires a one-tailed test. The other 80 students get a question except that it requires a two-tailed test. The one tailed students average 7.88 points and their standard deviation is 1.06 points. The two tailed students average 7.42 points and their standard deviation is 1.28 points. State the appropriate null and alternative hypothesis and then compute the p-value with the significance level of 0.10. Can you conclude that the mean score (population mean)1 on one tailed hypothesis test questions differs from the mean score (population mean)2 on two-tailed hypothesis test questions?
When the null hypothesis is true, the F test statistic is close to .When the null hypothesis is false, the F test statistic is most likely
You wish to test the following claim (Ha) at a significance level of a = 0.01. H.: u = 78.5 H.:u < 78.5 You believe the population is normally distributed, but you do not know the standard deviation. You obtain the following sample of data: data 64.5 63.5 72.4 68.2 58.3 65 What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) a O greater than a
In each of the situations, answer the following. a. b. State the null and alternative hypothesis in words. State the null and alternative hypothesis in symbols. What is the probability of committing type i error? State the conclusion when Ho is rejected. C. d. e. State the conclusion when Ho is not rejected. 1. A college dean claims that a bachelor's degree could be earned in an average of five years. Test the claim using 95% confidence level. 2. An FDA officer claims that Pharma XYZ's new caplet drug contains less than 300mg of paracetamol. Test the claim using 99% confidence level.
1.Which is the alternative hypothesis? a. There is a significant difference between a person's age and the number of hours he or she sleeps. b. There is no significant relationship between a person's age and the number of hours he or she sleeps. c. There is a significant relationship between a person's age and the number of hours he or she sleeps. d. There is no significant difference between a person's age and the number of hours he or she sleeps. 2. What is the df? 3. What is the critical value from the table?
When one changes the significance level of a hypothesis test from 0.10 to 0.05, which of the following will happen? Check all that apply. A. The chance that the null hypothesis is true changes from 0.10 to 0.05. OB. The test becomes less stringent to reject the null hypothesis (i.e. it becomes easier to reject the null hypothesis). c. It becomes harder to prove that the null hypothesis is true. OD. The chance of committing a Type I error changes from 0.10 to 0.05. ⒸE. The chance of committing a Type II error changes from 0.10 to 0.05. OF. It becomes easier to prove that the null hypothesis is true. ⒸG. The test becomes more stringent to reject the null hypothesis (i.e., it becomes harder to reject the null hypothesis).
A publisher reports that 52 % of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 350 found that 46 % of the readers owned a laptop. State the null and alternative hypotheses.
suppose you are running a poll about the proportion Of women over 40 who regularly have mammograms. You randomly sample 120 people and find out that 60 of them match condition you are testing.
