Question Help Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a girl, but assume that the method has no
effect, so the probability of a girt is 0.5. Assume that the groups consist of 33 couples. Complete parts () through (c) below.
a. Find the mean and the standard deviation for the numbers of girls in groups of 33 births.
The value of the mean is -- 16.6
(Type an integer or a decimal. Do not round.)
The value of the standard deviation is o-
(Round to one decimal place as needed)
b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.
Values of girls or fewer are significantly low.
(Round to one decimal place as needed.)
Values of girls or greater are significantly high.
(Round to one decimal place as needed.)
c. Is the result of 29 giris a result that is significantly high? What does it suggest about the effectiveness of the method?
The result significantly high, because 29 girls is
(Round to one decimal place as needed.)
girls. A result of 29 girls would suggest that the method

Atrain traveled for 1.5 hours to the first station, stopped for 30 minutes, then traveled for 4 hours to the final station where it stopped for 1 hour. the total distance traveled is a function of time. which graph most accurately represents this scenario? a graph is shown with the x-axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at the origin and moves upward for 1.5 hours. the line then continues upward at a slow rate until 2 hours. from 2 to 6 hours, the line continues quickly upward. from 6 to 7 hours, it moves downward until it touches the x-axis a graph is shown with the axis labeled time (in hours) and the y axis labeled total distance (in miles). a line is shown beginning at the origin. the line moves upward until 1.5 hours, then is a horizontal line until 2 hours. the line moves quickly upward again until 6 hours, and then is horizontal until 7 hours a graph is shown with the axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at the y-axis where y equals 125. it is horizontal until 1.5 hours, then moves downward until 2 hours where it touches the x-axis. the line moves upward until 6 hours and then moves downward until 7 hours where it touches the x-axis a graph is shown with the axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at y equals 125 and is horizontal for 1.5 hours. the line moves downward until 2 hours, then back up until 5.5 hours. the line is horizontal from 5.5 to 7 hours
