Vicki would like to estimate the probability of tails coming up fewer than 2 times in 3 coin flips. to do this, she has a computer randomly select 0 or 1 three times, with 0 representing heads and 1 representing tails. the results of 15 trials are shown in the table.

what is vicki's estimated probability, based on this simulation?

enter your answer as a fraction, in simplified form, in the box.

(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
