Mattel wanted to examine how popular 7 new toy prototypes would be to 9 year old boys. mattel brought in 40 boys who were nine years old and allowed them to play with each toy prototype for 15 minutes (so each prototype was available for 15 minutes). other traditional toys were also in the room, and the percentage of time each boy played with the prototype was collected for each boy. what statistical test should be used of analyze this data?

One proportion z test

Step-by-step explanation:

For this case, we can use the one proportion z test, this test is used when we have 2 categories and we want to see how significantly different is one from the other.

In this case, our two categories would be the toy prototype and the traditional toys.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
