In randomized, double-blind clinical trials of a new vaccine, children were randomly divided into two groups. subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. after the second dose, 119 of 620 subjects in the experimental group (group 1) experienced fever as a side effect. after the second dose, 93 of 642 of the subjects in the control group (group 2) experienced fever as a side effect. does the evidence suggest that a higher proportion of subjects in group 1 experienced fever as a side effect than subjects in group 2 at the alphaequals0.05 level of significance?

The perimeter of a shape is all of the sides added up.

On a rectangle there are 2 short sides(width) and two longs sides (length)

The width is 4
The length is 10

10+10=20
4+4=8
20+8=28

The perimeter of the rectangle is 28inches
