Meg rolled a fair six-sided die 28 times. the table below shows the number of times each number was rolled: number cube experiment number on the cube number of times appeared 1 2 2 7 3 9 4 4 5 6 6 0 according to the results in the chart, what is the experimental probability of getting a number less than 3 on the die? 19 over 28 9 over 28 7 over 28 2 over 28

If 1 is divided by the sum of y& 4.the result is equal to 3 divided by 4, find the value of m

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
