Answer:
The best conclusion is that we are 90% that the true population proportion of Republicans that voted for Mitt Romney is between 0.7273 and 0.8106.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
The 90% confidence interval for the proportion of Republican voters that had voted for Mitt Romney is (0.7273, 0.8106). The best conclusion is that we are 90% that the true population proportion of Republicans that voted for Mitt Romney is between 0.7273 and 0.8106.
88+36 is the same as 90+34 because, their sums both equal 124.
Answer:3
Step-by-step explanation:
Answer:
A.) y = 20x
B.) 21 minutes
Step-by-step explanation:
y = mx + b; y2 - y1/ x2 - x1 = m (slope)
A.) If a factory can build 20 cars per hour, the first point would be (1, 20). To find the slope (m), divide the y-axis by the x-axis: 20/1 = 20.
B.) Before we can do this problem, we must first convert the hours to minutes. 1 hour = 60 minutes. Then we divide the minutes by the number of cars. 60 ÷ 20 = 3. That means the factory builds 1 car every 3 minutes. Multiply the number of cars, 7, by the number of minutes it takes to make one car: 7 • 3 = 21.
