Explanation Given: The expression is, 7 , 700 9 , 286 + 3 , 900 _ Procedure used: Rounding whole numbers “Step 1. Identify the place value of the digit you want to round. Step 2. If the digit to the right of the identified digit in Step 1 is 5 or more, increase the identified digit by 1 (round up). If the digit to the right is less than 5, do not change the identified digit. Step 3. Change all digits to the right of the rounded identified digit to zeros.” Calculation: Consider the numbers 7,700, 9,286 and 3,900. Clearly, the leftmost digit in 7,700 is 7, in 9,286 is 9 and in 3,900 is 3. Note that to round a number all the way, you round to the first digit of the number (the leftmost digit) and have only one nonzero digit remaining in the number. Hence, the number 7,700 becomes 8,000 as the digit next to 7 is 7 which is greater than 5, 9,286 becomes 9,000 as the digit next to 9 is 2 which is less than 5 and 3,900 becomes 4,000 as the digit next to 3 is 9 which is greater than 5. Compute the estimated value of the expression as follows

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

7.2.10 Researchers in the Hopkins Forest also count the number of maple trees (genus acer) in plots throughout the forest. The following is a histogram of the number of live maples in 1002 plots sampled over the past 20 years. The average number of maples per plot was 19.86 trees with a standard deviation of 23.65 trees. a. If we took the mean of a sample of eight plots, what would be the standard error of the mean? b. Using the central limit theorem, what is the probability that the mean of the eight would be within 1 standard error of the mean? c. Why might you think that the probability that you calculated in (b) might not be very accurate? 2. A normal population has mean 100 and variance 25. How large must the random sample be if you want the standard error of the sample average to be 1.5?

Answer questions 7.3.10 and 7.3.12 respectively 7.3.12. Suppose that two independent random samples (of size n1 and n2) from two normal distributions are available. Explain how you would estimate the standard error of the difference in sample means X1 − X2 with the bootstrap method.
