3) 38% of all people wish there were not so many chocolate chips in each Chips Ahoy chocolate chip cookie. A random sample of 1000 people is taken. a) Describe the sampling distribution of the sample proportion, p. (10 points) b) 400 out of 1000 people in a random sample said they wish there not so many chocolate chips. in each Chips Ahoy chocolate chip cookie. Find the sample proportion, p. (10 points) c) What is the probability 400 or more out of 1000 in a random sample will say they wish there not so many chocolate chips in each Chips Ahoy chocolate chip cookie. (20 points) d) Would taking a random sample of 1000 people and finding 400 who wish there were not so many chips in a Chips Ahoy chocolate chip cookie be unusual if 38% of all people wish there were not so many chocolate chips in a Chips Ahoy chocolate chip cookie? Justify your answer. (7 points) e) Would a random sample where 400 out of 1000 people said they wish there were not so many chips in a Chips Ahoy cookie be evidence that more than 38% of all people wish that?
