Question

mean number of grams of saturated fat for this sample of 36 McDonald's breakfast foods. Based on the grams of saturated fat for this sample of 36 McDonald's breakfast foods. g distribution of the resulting mean number of (10 points) Suppose a simple randonm 17b. (10 points) Suppose a simple random sample of 36 McDonald's breakfast foods are purchased. Of interest is the mean number of grams of saturated fat for this sample of 36 McDonald's breakfast foods. Based on the sample of 36 McDonald's breakfast foods is between 8.5 and 10 grams? above, what is the probability that the mean number of grams of saturated fat for this

Explanation / Answer

(a) A simple random sample of 36 McDonalds breakfast foods are purchased. Of interest here is the mean number of grams of saturated fat . Now the sampling distribution mean number of grams of saturated fat for this sample of 36 stores, will follow a normal distribution. with all the means of the different simple random samples coming togther to create an expected value which will eual the mean of the population

(b) So, if we know the expected value of the mean for the population then we can calcluate the corresponding z statistic by using the formula 8.5 - E(U)/ Std. dev of poplulation =z1

We can compute a similar statistic for 10 grams as 10 - E(U) / Std. dev of poplulation =z2

Now the prob that the mean for the simple random sample of 36 items will lie between 8.5 and 10 grams is the area the std. normal curve between z1 and z2
