Question 21 of 24 (1 point) 6.3 Section Exercise 8 A survey found that the American family generates an average of 17.2 pounds of glass garbage each year. Assume the standard deviation of the distribution is 2.5 pounds. Find the probability that the mean of a sample of 58 families will be between 17.1 and 18.1 pounds.

2.) In a recent year, Delaware had the highest per capita annual income with an average of $51,800 and Annual per capita income is normally distributed in Delaware. $1850. (a) If a resident is randomly selected, what is the probability that their income is less than $50,000? Let X be the salary of a randomly selected Delaware resident. Write an inequality that represents the scenario described in (a). DIX< 50.000)=0.3553 Properly shade the bell, set-up, and solve the problem. m=51,800...
