The average number of pages for a simple random sample of 40 physics textbooks is 435. The average number of pages for a simple random sample of 40 mathematics textbooks is 410. Assume that all page length for each types of textbooks is normally distributed. The standard deviation of page length for all physics textbooks is known to be 100, and the standard deviation of page length for all mathematics textbooks is known to be 100.Assuming that on average, mathematics textbooks and physics textbooks have the same number of pages, what is the probability of picking samples of these sizes and getting a sample mean so much higher for the physics textbooks (one-sided p-value, to four places)?

Which statement about this product is true? 0.36×(−758)A.) It is less than −758-758 because multiplying by a number less than 11 gives a smaller number.B.) It is greater than −4-4 because 0.36×(758)0.36×758 is less than 12×812×8.C.) It equals −758-758 because 36363636 equals 11, and 11 times any number equals that number.D.) It equals 00 because 0.360.36 rounded to the nearest whole number is 00, and 00 times any number is 00.
