Question 4 (1 point)
Ethan's class is handing out balloon arrangements consisting of 4 balloons each. Each
balloon has an equally likely chance of being red, blue, or yellow. Ethan created a
spinner to simulate this probability. Here is Ethan's data from 30 trials of 4 spins on
the spinner (r = red, b = blue, y = yellow):
ybrr bybb rbbb rrry rbbb rryy yybb ryry ryyr rbyr ryyr rryy yrby bbyy byyr byyr
byyb rbby ybry rryy rbrr rybb bbbr rrbrybry ryrr rryb rrrb rryr
According to this data, what is the experimental probability that an arrangement will
consist entirely of balloons that are the same color?

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
