不 The table shows the heights of some of the tallest roller coasters in a certain area. Complete parts (a) through (c) below. Roller Coaster Height (in feet) Roller Coaster 1 441 Roller Coaster 2 424 Roller Coaster 3 418 Roller Coaster 4 Roller Coaster 5 336 301 a. Find and interpret (report in context) the mean height of these roller coasters. Select the correct choice below and fill in the answer box within your choice. (Type an integer or a decimal. Do not round.) OA. The typical height of all of the roller coasters in the world is ft. B. The typical height of the tallest roller coasters in this area is OC. The typical height of all of the roller coasters in this area is ft. ft. OD. The typical height of the tallest roller coasters in the world is ft. b. Find and interpret the standard deviation of the height of these roller coasters. Select the correct choice below and fill in the answer box within your choice. (Type an integer or decimal rounded to the nearest tenth as needed.) OA. The standard deviation of the height of the tallest roller coasters in the world is OB. The standard deviation of the height of all of the roller coasters in the world is OC. The standard deviation of the height of all of the roller coasters in this area is OD. The standard deviation of the height of the tallest roller coasters in this area is ft. ft. ft. ft. c. If roller coaster 1 was only 424 feet high, how would this affect the mean and standard deviation you calculated in (a) and (b)? Then recalculate the mean and standard deviation using 424 as the height of roller coaster 1. Choose the correct answer below.

If roller coaster 1 was only 424 feet high, how would this affect the mean and standard deviation you calculated in (a) and (b)? Then recalculate the mean and standard deviation using 424 as the height of roller coaster 1. Choose the correct answer below. OA. The mean and standard deviation will decrease. OB. The mean will increase and the standard deviation will decrease. OC. The mean will decrease and the standard deviation will increase. OD. The mean and standard deviation will increase. Now recalculate the mean and standard deviation using 424 as the height of roller coaster 1. The new mean is ft. The new standard deviation is ft.
