Both questions please

Question 7 Type numbers in the boxes A machine is designed to fill 16-ounce bottles of shampoo. When the machine is working properly, the amount poured into the bottles follows a normal distribution with mean 16.05 Part 5 points ounces with a standard deviation of 2005 ounces. Purt 2: 5 points If four bottles are randomly selected each hour and the number of ounces in each bottle is measured, then 95% of the means calculated should occur in what interval? Hint: the standard deviation rule says that 95% of the observations are within how many standard deviations away from the mean? Round answers to four decimal places. 10 points Question 8 Type numbers in the boxes Suppose that the distribution for total amounts spent by students vacationing for a week in Florida is normally distributed with a mean of 650 and a standard deviation of 120. Suppose 10 points you take a simple random sample (SRS) of 40 students from this distribution. What is the probability that a SRS of 40 students will spend an average of between 600 and 700 dollars? Round to five decimal places
