Problem 2E

Suppose that among gifted seventh-graders who score very high on a mathematics exam, approximately 20% are left-handed or ambidextrous. Let X equal the number of left-handed or ambidextrous students among a random sample of n = 25 gifted seventh-graders. Find P(2 < X < 9)

(a) Using Table II in Appendix B.

(b) Approximately, using the central limit theorem.

REMARK Since X has a skewed distribution, the approximation is not as good as that for the symmetrical distribution where p = 0.50, even though np = 5.

Step-by-Step Solution:
Step 1 of 3

Financial Accounting 2.1 The rules of debit and credit were debit stands right and credit stands left of a chart. In the account there is a record of increases and decreases in asset, liability, equity, revenue, or expense item. The account consists of the title, the left debit side, and the right credit side. It may be difficult to understand without an illustration. So all the debit and credit rules are as so: Debit increases for the increases ofAssets, Expenses, and Dividend. Credit increases for the increase of Liabilities, Common Stock, Retained Earnings, and Revenue. Like how it’s illustrated below. When solving
