What are the standard time and date at (40°N, 118°W) when the standard time at (35°N, 65°W) is 6 P.M. on October 8?
Time difference between each degree longitude is 4 minutes.
Time difference between 118 deg W and 65 deg W is
4*(118-65) = 212 minutes = 3 hr 32 minutes.
118 deg W lags behind 65 deg W.
Time at 118 deg W is 6PM - 3 hrs 32 minutes = 5:28 PM
As it does not cross 12 night , date remains same, that is 8
October.
Hence date and time at 118deg W, when standard time at 65 deg W is
6:00 PM on 8th oct. is
5:28 PM, 8th October

Mark wants to estimate the mean length of time (in minutes) all Middle School students spend reading online books. To determine this estimate, he took a random sample of 15 people and obtained the following results: 40, 110, 56, 20, 15, 10, 82, 60, 90, 118, 35, 25, 5, 65, 30. The population of times is normally distributed. What is the margin of error at the 95% confidence level if the population standard deviation is 8 minutes? Round off you...
