1) Lights Out Larry is the all-time leading 3-point shooter for his high school basketball team. One reason is that he is always practicing his 3-point shots. At the end of each practice, he attempts 250 3-point shots before turning the Lights Out and going home. The data below represents the number of shots Lights Out Larry made after each of the 40 practices this past season. 182 174 177 182 171 171 191 178 193 170 178 173 161 163 190 179 179 182 198 186 168 169 188 171 182 177 185 150 175 178 169 159 185 181 162 174 158 170 196 165 a.

I need help i don’t understand this at all
c. Is it reasonable to assume that this data is normally distributed? Explain your answer. Yes, this data has normal distribution because it appears to have a bell shape, which means that the majority of the time, Larry made between 170 and 180 3-point shots, with few practice days where he made fewer shots and few practice days where he made lots (close to 200 shots) of shots. 2) There are many different types of hot dogs produced in the U.S. The data to the Beef Poultry right represents the published mean calorie contents of the various brands that Y produce beef hot dogs and the mean calorie contents of various brands that 186 129 produce poultry hot dogs. (Treat these as samples.) 181 132 a. Compute the mean calorie content for each type of hot dog. (beef and 176 102 poultry) 149 106 3137 184 94 Веef, x: = 156.85 = 156.9 20 190 102 158 87 2019 Poultry, y: 17 = 118.76 = 118.8 139 99 175 107 b. Compute the median calorie content for each type of hot dog.

Compute the standard deviation for the calorie content for each type of hot dog. (beef and poultry) Standard Deviation Beef: s, = 22.642 Standard deviation Poultry: Sy = 22.55 d. Compute the coefficient of variation for the calorie content for each type of hot dog. (beef and poultry) 22.642 22.55 Beef: CV = * 100 = 14.435% Poultry: CV = * 100 = 18.99% 156.85 118.765 e. Compute the five number summary for the calorie content for each type of hot dog. (beef and poultry) Beef: 111, 140, 152.5, 178.5, 190 Poultry: 86, 100.5, 113, 142.5, 152 f.
