an engineer calculating where to place a diagonal support because the Pythagorean theorem is for right triangle situations. In this case the diagonal support would be like the hypotenuse
Answer:
138
Step-by-step explanation:
Population standard deviation = 
.95 probability of estimating the population mean monthly income within a margin of $20
So, Significance level = 1-0.95 = 0.05
α =0.05
Margin error = 20

Z at 0.05 = 1.96




So, n = 138
Hence sample size should be 138 selected to obtain a .95 probability of estimating the population mean monthly income within a margin of $20
In a softball game, the odds are only win or lose the game. When 2 games are already being considered, the elements in the sample space are already 2 in each set. The sets are {W,W}, {W,L}, {L,W} and {L,L}. Hence, there are 4 sets all in all to describe the odds of the two games.
