2. The formula method is applicable in this case as the histogram exhibits a bell-shaped pattern, suggesting a normal distribution. Additionally, the bootstrap sample histogram also demonstrates an approximately normal distribution. 3. Population Mean = 43.44 Bootstrap sd= 3.87 z = 2 Standard of error: 3.87*2=7.74 Upper bound = 43.44 +7.74= 51.18 Lower bound = 43.44 -7.74 = 35.7 4. We are 95% confident that the average number of texts that all OSU students send is between 35.7 texts and 51.18 texts per day 5. I would say that it could be a little incorrect of 51.18 of texts so we would be still having a % error of 95. 6. The data we utilized came solely from STATS351 students, which isn't a random sample and, as a result, may not provide an accurate representation of all OSU students. PART II 7. The variable of interest is whether students at OSU have sent a text while driving or not. It is categorical as the answer is yes or no. 8.Proportion is 0.662 The notation symbol is p: p=0.662 9.

10. We can use the formula method because the shape looks and bell shaped. 11.p= 0. 662,bootstrap SD: 0.024, z=2 Standar error: 0.0243*2= 0.048 Upper: 0. 662+0.048=0.71 Low: 0.662-0.048=0.614 12. We are 95% confident that the mean of all OSU students who have sent a text message while driving is between 0.614 and 0.71.
