According to a study conducted by Ace Computers, 59% of men and 70% of women say that weight is an extremely/very important factor in purchasing a laptop computer. Suppose this survey was conducted using 374 men and 481 women. Do these data show enough evidence to support the conclusion that there is no difference in the proportion of men and women who think weight is a factor in purchasing a laptop? Use a 5% level of significance.
Below is the step by step solution:
Step 1. Calculate the # of men(X1) and the number of women (X2) who say laptops weight is an important factor in purchase decision making:
X1 = p1 cap * n1 = 0.59 * 374 = 220.66
X2 = p2 cap* n2 = 0.70 * 481 = 336.7
Step 2. Compute weighted estimate of combined ...
This solution highlights step by step method of solving statistical problems involving proportions.
