4. The heаdline in the Sаcrаmentо Bee newspaper read, “Wоmen appear tо be better investors than men in study” (Jack Sirard, April 24, 2005, p. D1). The conclusion was based on a telephone poll of 500 randomly selected men and 500 randomly selected women. One quote in the article was that “men are much more likely to stick with a losing investment than women are (45% vs 37%). Of the 500 male investors, 225 decided to stick with a losing investment. Of the 500 female investors, 185 decided to stick with a losing investment. The following table displays the data for these two groups. Group n Number who stick with a losing investment Male Investors 500 225 Female Investors 500 185 Test the research hypothesis that the population proportion of male investors who decided to stick with a losing investment is more than that of female investors who decided to stick with a losing investment. (While answering the following sub-parts of this question, you will be including the null and alternative hypothesis, the test statistic, the p-value (a visualization and an interpretation), your statistical decision, and your conclusion in the context of the problem.) (a) Which of the following best represents the hypothesis for Step 1 of the hypothesis test?

Cоnsider the fоllоwing Booleаn function: G(а, b, c, d) = ∏ M(0, 1, 8, 9, 10, 11, 14) Drаw the proper truth table in order for this Boolean function. What should the output be in your Truth table and the corresponding square in your K-map at each maxterm location? Draw and fill the proper k-map(s) (that matches the labels of the truth table and include all values). Show the proper grouping in your k-map(s) to find the optimal (minimal) PoS Boolean expression. Write the resulting optimal (minimal) PoS Boolean expression. Draw the optimal PoS 2-level circuit and state the name of the 2-level circuit. Redraw the logic circuit as a 2-level logic circuit using NOR gates only. Write the Boolean expression of a 2-level logic circuit using NOR gates only.
