The following data represent the high-temperature distribution for a summer month in a city for some of the last 130 years. Treat the data as a population. Complete parts (a) through (c)- Temperature ("F) 50-59 60-69 70-79 80-89 90-99 100-109 Days 318 1408 1481 470 11 (a) Approximate the mean and standard deviation for temperature. H= OF (Round to one decimal place as needed.) G=OF (Round to one decimal place as needed.) (b) Draw a frequency histogram of the data to verify that the distribution is bell shaped. Construct a frequency histogram. Choose the correct graph below. O A. O B. O C. O D. A Frequency A Frequency A Frequency AFrequency 1750- 1750- 1750- 1750- 50 110 50 110 50 110 50 110 Temperature (deg F) Temperature (deg F) Temperature (deg F) Temperature (deg F) Is the distribution bell shaped? O A. Yes, the frequency histogram of the data is bell shaped. O B. No, the frequency histogram of the data is skewed left. O C. No, the frequency histogram of the data is uniform. O D. No, the frequency histogram of the data is skewed right. (c) According to the Empirical Rule, 95% of days in the month will be between what two temperatures? OF and OF (Round to one decimal place as needed. Use ascending order.)
