We are given the following data:
Sample Size = n = 1000
Sample Mean = u = 15 hours
Population Standard Deviation = s = 2 hours
Since we know the population standard deviation, we can use z distribution to find the confidence interval about the mean. z value for 95% confidence interval is 1.96.
Formula for the confidence interval is:
![(u-z\frac{s}{\sqrt{n}} , u+z\frac{s}{\sqrt{n}})](https://tex.z-dn.net/?f=%20%28u-z%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%20%2C%20%20u%2Bz%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%29%20)
Using the values in the formula, we get:
![(15-1.96\cdot\frac{2}{\sqrt{1000}}, 15+1.96\cdot\frac{2}{\sqrt{1000}})\\ \\ (14.88,15.12)](https://tex.z-dn.net/?f=%20%2815-1.96%5Ccdot%5Cfrac%7B2%7D%7B%5Csqrt%7B1000%7D%7D%2C%20%2015%2B1.96%5Ccdot%5Cfrac%7B2%7D%7B%5Csqrt%7B1000%7D%7D%29%5C%5C%20%5C%5C%20%20%2814.88%2C15.12%29%20)
Therefore, the 95% confidence interval about the population mean is 14.88 hours to 15.12 hours. So B option is the correct answer.
Rick started with 10/10 of the grapes because he had all of them at the start.
Then he gave 2/10 and 4/10 of the grapes away.
10/10 - 2/10 - 4/10 = 4/10 = 2/5 left
answer: Rick had 2/5 of the grapes left.
