For this project you need to obtain some plain M&Ms.
1. Data collection: Carefully inspect at least 200 M&Ms, sorting them into two piles, with non
defective M&Ms in one pile and defective M&Ms in a second pile. A defective M&Ms is one
with missing letters, chips, or cracks. If your bag has less than 200 M&Ms obtain some more.
command
What is your sample size?
What is the number of defective M&Ms?
2. With your sample calculate a 95% confidence interval for the population proportion of defective
plain M&Ms by hand (SHOW WORK). Please write a complete sentence. Round to 3 decimal

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
