The null and alternative hypotheses for a hypothesis test of the difference in two population means are:
Null Hypothesis:mu 1 equals mu 2
Alternative Hypothesis: mu 1 is less than mu 2
Notice that the alternative hypothesis is a one-tailed test. Suppose ttest_ind method from scipy module is used to perform the test and the output is (3.25, 0.0043). What is the P-value for this hypothesis test? Select one.

- A smoke alarm is supposed to make noise when there is a fire and stay silent when there is no fire. Designers of a smoke detector would use the following hypotheses: H0: There is no fire. HA: There is a fire. If you were designing a smoke detector, would you want to pick a large alpha or small alpha? Group of answer choices A Type I error is worse than a Type II error, so I would pick a large alpha. A Type I error is worse than a Type II error, so I would pick a small alpha. A Type II error is worse than a Type I error, so I would pick a large alpha. A Type II error is worse than a Type I error, so I would pick a small alpha.arrow_forwardenter the number of the expression indicating the null hypothesis and enter the number of the expression indicating the alternative hypothesis calculate a z and enter to the second decimal place enter the critical value for z (if using the .01 alpha leave) what do you make about the null? is this an effect or chance?arrow_forwardA veterinary study of horses looked at water sources for horses, and the investigators found that horses received water from a well, from city water, or from a stream.

- Question 21, Multiple choice below. 21. The financial aid director of a large college reports that 38% of the students enrolled are receiving some sort of financial aid. A researcher claims the percentage is lower and finds (from sampling) 29 out of 116 students are receiving some sort of financial aid. At alpha = 0.05, decide whether the financial aid director's report that 38% of the students are receiving some sort of financial aid holds up. For question #21 (multiple choice), choose the alternative hypothesis. For #22, fill in the space provided with your calculated value for p hat. For question #23, fill in the space provided with your calculated z-value from the information provided. For #24, answer True or False with regard to rejecting the null hypothesis.arrow_forwardAssume that the following tables are the results of Diagnostic tests. Why do you use the following test?
