A total of 250 children are randomized to either the new drug or placebo (125 per group). There are 63 boys assigned to the new drug group and 58 boys assigned to the placebo. Is there a statistically significant difference in the proportions of boys assigned to the treatment: Apply the appropriate test at a 5% level of significance?
1) Critical Value = +/-
2) Computed statistics =
3) Based on comparing the computed statistics to the critical value of the following is (are) true?
a) There is significant evidence, alpha = 0.05, that there is a difference in the proportions of boys assigned to the treatments.
b) There is not significant evidence, alpha = 0.05, that there is a difference in the proportions of boys assigned to the treatments.
c) Statistically speaking the difference in the proportions of boys assigned to the treatments is 0
d) B & C
