Based on the information given: Provide your calculation of the total numbers of teenagers who drive a car on the road. i. ii. Based on your understanding what is the probability of teenagers getting involved in accidents during both day and night times? iii. Interpret the probability of teenagers who were not getting involved in accidents during day time.arrow_forwardA researcher believes that the so-called “sugar high” is not real. He gathered 30 adolescents and recorded their activity level in the scale of 0 – 100 (0 = not active and 100 = super active). First, he recorded participants’ activity level before they consumed candy. After recording their pre-sugar activity level, the researcher gave out 5 Snickers bars to participants. Then, he recorded their post-sugar activity level. The average difference between post-sugar and pre-sugar activity level is 50 (i.e., the activity levels are higher after sugar than prior to it) with a standard deviation of 10. A).
