Hi I attched the solution as an attachment. Hope this helps you.
12. Are 14% of M&M Candies Yellow? Mars, Inc., claims that 14% of its M&M plain candies are yellow, and a sample of 100 such candies is randomly selected.
a. Find the mean and standard deviation for the number of yellow candies in such groups of 100.
x = number of yellow M&Ms; n = 100; p = 0.14
Standard Deviation: ___________
b. Data Set 13 in Appendix B consists of a random sample of 100 M&Ms in which 8 are yellow. Is this result unusual? Does it seem that the claimed rate of 14% is wrong?
Unusual values are those outside ______(insert the formula)
Now plug that in for max and min values:
Minimum usual value:_________
Maximum usual value: ________
Conclusion: Now you'll provide an interpretation and a summary statement
