9. Two random samples were taken to determine left foot length of female versus male bears based on measuring their tracks. Numerical summaries of the data are given. Use them to answer the questions. Male Female Mean 9.4 in Standard error 0.162 Median 9.115 Std dev 1.81 Sample Variance 3.26 ange 9.78 Min 4.57 Max 14.35 Sum 1145.77 Count 124 Mean 12.77 in Standard error 0.104 Median 12.77 Std dev 1.44 Sample variance 2.07 Range 7.67 min 9.26 max 16.93 sum 2439.11 count 191 A) Do male bears have longer feet than female bears? Are you sure? B) Give a range of values in which you would expect to find 95% of all bears’ feet lengths. Explain why you picked this range. C) What is the shape of the distribution of bears’ feet lengths? Explain.
