A survey was carried out in which it was desired to determine whether there is a relationship between
being in favour of the death penalty and whether marijuana should be made legal or not.
A two-way table
of the results is given below:
======================================...
_________ "Marijuana"________|
===================| Legalize | Do not legalize | Total |
|Death | In favour |.......... ........19 | ...... 34....... | ............ 53 |
|penalty | Oppose |.................10 | ...... 17 ..... |.............. 27 |
======================================...
Total | .......... ......................... 29 | ...... 51 | .....80 |
======================================...
A hypothesis test is carried out. Use α = 0.01.
Consider the following statements. Which one of the statements below is correct?
(1) The null- and alternative hypotheses are
H0 : Opinion about marijuana and death penalty are related.
Ha : Opinion about marijuana and death penalty are not related.
(2) If the null hypothesis is true, the expected counts for legalizing marjuana and opposing the death
penalty are 19.21.
(3) The χ2-test statistic is equal to 0.011.
(4) The p-value or p-value range is p < 0.50.
(5) We can reject H0 at the 1% significance level. There is no relationship between the opinion about
marijuana and the death penalty.
