Is the statement Ho: 14 = 6 a valid null hypothesis? O No, equalities are not permitted in the null hypothesis. O Yes, this is a statement that compares a parameter to a value. O No, there is no parameter. O Yes, this is a statement that compares 2 values.

When the null hypothesis is not rejected, it is O possible a Type I error has occurred. not possible a Type II error has occurred. possible a Type II error has occurred. O possible either a Type I or a Type II error has occurred.

Which set of numbers would correspond to a hypothesis test with the greatest power? Cohen's d = 0.6 & n = 500 O Cohen's d = 0.6 & n = 50 O Cohen's d = 0.5 & n = 50 O Cohen's d = 0.5 & n = 500

Claim: A minority of adults would erase all of their personal information online if they could. A software firm survey of 453 randomly selected adults showed that ​45% of them would erase all of their personal information online if they could. Complete parts​ (a) and​ (b) below. a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information. b. Identify the null and alternative hypotheses.

5. Conclusions True or false: In hypothesis testing, it is never valid to form a conclusion of supporting the null hypothesis.

Examine the given statement, then express the null hypothesis Ho and the alternative hypothesis H1 in the symbolic form: (1) The mean weight of women who won a beauty pageant is equal to 120 lbs. (2)  There are more then 97% of  LBCC students have computers. (3( There are at least 50% of LBCC students have a job while studying>

If the researcher wants to do a 2 tailed hypothesis test based on the data to generalize the relationship, what would the null and alternative hypothesis be? (in words and symbol notation).

Whenever possible, the alternative hypothesis should O incorporate the researcher's hypothesis. O not include an equality. all of the above. be the complement to the null hypothesis.

Let’s assume the average income for all majors in the School of Engineering is $80,000. However, the chair of the Computer Science department thinks their students earn more than that. Please choose the appropriate null and alternative hypotheses if the chair wanted to test this belief. a. H0: u <=80,000 Ha: u > 80,000 b. H0: u= 80000 Ha: u not= 80000 c. H0: u >80000 Ha: u < 80000 d. H0: u >80000 Ha: < 80000 e. None of the above.

Provide an appropriate response. If we fail to reject the null hypothesis when the null hypothesis is false, then we have made a Type B error Type I error Correct decision Type II error
