2 points liat variable to Z scores a standard normal distribution or not? Explain. 2 - Value - Mear Stand. Del 5. The annual profits of small business owners in the town of Brownville has a normal distribution wit of $60,000 and standard deviation $5000. 8 a. Calculate Z scores for the following four amounts: $50,000, $55,000, $65,000, and $70,000. b. What proportion of the distribution falls below $50,000? c. What proportion of the distribution falls between $55,000 and $50,000? d. What proportion of the distribution falls between $60,000 and $65,000? e. What proportion of the distribution falls above $65,000? f. What is the probability that a randomly selected business owner in this distribution has a profit betw $50,000 and $70,000? [Hint: Remember when I am asking proportion, I mean the area under the curve in proportion as pro the Normal Curve Table at the back of the Book].
