Logs of about the same sizes (lengths and diameters) are so arranged that the stack approximates the shape of an isosceles trapezoid. The number of logs in two consecutive layers differs by two (2). If there are 98 logs in the bottom layer and 20 logs on the top, how many logs are in the stack?

Length of a rod: Engineers on the Bay Bridge are measuring tower rods to find out if any rods have been corroded from salt water. There are rods on the east and west sides of the bridge span. One engineer plans to measure the length of an eastern rod 25 times and then calculate the average of the 25 measurements to estimate the true length of the eastern rod. A different engineer plans to measure the length of a western rod 20 times and then calculate the average of the 20 measurements to estimate the true length of the western rod. Suppose the engineer who collected 25 measurements for the eastern rod has a mean length of 23.9 feet with a standard deviation of 0.5 feet. The critical T-value for a 90% (one-sample) confidence interval with df = 24 is T=1.71. Which of the following is the resulting 90% confidence interval? (23.73 , 24.07) (23.05, 24.76) (23.80, 24.00)
