Ma'am / Sir, please help me. In the picture, you can see what is asked in the problem (a,b,c....)letter a answer was already attached below

9 - ) No. of wheels Freeray ( x ) (y ) - O - OH = Y - total: 28 1 2 3 45 6 78 9 1000 social robots walk or roll? Refer to the International Conference on Social Robotics (Vol. 6414, 2010) study on the current trend in the design of social robots, ' ' \"bgl'xmb'em Recall that in a random sample of social robots obtained through a web search, 28 were built with wheels. The number of wheels on each of the 28 robots is listed in the accompanying table. 3. Generate a histogram for the sample data set. Is the dis- tribution of number of wheels mound-shaped and sym- metric? . Find the mean and standard deviation for the sample data set. . Form the interval, 7 :1: 2s. . According to Chebychev's Rule, what proportion of sample observations will fall within the interval, part c? . According to the Empirical Rule, what proportion of sample observations will fall within the interval, part c? . Determine the actual proportion of sample observations that fall within the interval, part c. Even though the his- togram, part a, is not perfectly symmetric, does the Em- pirical Rule provide a good estimate of the proportion? .ROBOTS 44333642221333 34432822343342 Source: Chew, 8., ct a]. \"Do social robots walk or roll?\
