Answer:
DECISION SCIENCE Assume more restrictions. The books pass through two departments: Graphics and Printing, 1. before they can be
sold, X requires 3 hours in Graphics and 2 hours in printing. Y requires 1 hour in graphics and 1 hour in printing. There are 21 hours available in graphics and 19 hours in printing respectively. Solve for x and y.
1 answer:
Answer: The value of x and y are 2 and 15 respectively.
Step-by-step explanation:
Since we have given that
Number of hours available in graphics = 21 hours
Number of hours in printing = 19 hours
Number of hours required by x in graphics = 3
Number of hours required by x in printing = 2
Number of hours required by y in graphics = 1
Number of hours required by y in printing = 1
According to question, we get that
Using the graphing method, we get that
x = 2 and y = 15
Hence, the value of x and y are 2 and 15 respectively.

Answer:
There is a significant difference between the two proportions.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for difference between population proportions is:
Compute the sample proportions as follows:
The critical value of <em>z</em> for 90% confidence interval is:
Compute a 90% confidence interval for the difference between the proportions of women in these two fields of engineering as follows:
There will be no difference between the two proportions if the 90% confidence interval consists of 0.
But the 90% confidence interval does not consists of 0.
Thus, there is a significant difference between the two proportions.
