- You accept the alternative hypothesis when you reject the null hypothesis. justify the above statement?Which is the alternative hypothesis?The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.02 level that the drug stays in the system for more than 382 minutes. After performing a hypothesis test, she decides to reject the null hypothesis.
- State the null and the alternative hypothesis. Ho:I need help understanding the null hypothesis and when to “reject” or “fail to reject” it. I got 5.77 in 3df and a critical value of 7.82.The average American consumes 9.8 liters of alcohol per year. Does the average college student consume less alcohol per year? State your null and alternative hypothesis H0:H0: Ha:Ha:
- If you are not able to prove the alternative hypothesis, this means the null hypothesis is correct.

- The form of the alternative hypothesis can beDecide whether each of the following statements make sense, or is clearly true, or does not make sense, or is clearly false explain your reasoning. We began to study with the null hypothesis, stating that the toxic waste of had no effect on the residents nearby in our study, approve this hypothesis to beFacebook: A study showed that two years ago, the mean time spent per visit to Facebook was 20.8 minutes, Assume the standard devlation is o= 8.0 minutes. Suppose that a simple random sample of 107 visits was selected this year and has a sample mean of x= 18.8 minutes. A social scientist is interested to know whether the mean time of Facebook visits has decreased. Use the a=0.10 level of significance and the critical value method with the table. (a) State the appropriate null and alternate hypotheses. (b) Compute the value of the test statistic. (c) State a conclusion. Use the a = 0.10 level of significance.
