Answer:
The answer is 3 cups of orange juice.
Step-by-step explanation:
So basically it says every 1/4 cup of water, you need 3/4 cups of orange juice. Now, 1 cup of water is the same thing as 4/4 cups of water. To get to 4/4 from 1/4, you need to multiply 1/4 by 4. Because of that, you need to multiply 3/4 by 4 as well. 3/4 * 4 is 3, and that's how you get your answer.
Answer:
Step-by-step explanation:
Given that Home sales has 95% confidence interval to estimate the average loss in home value.
a) If std deviation of losses doubles as 3000 from 1500, we have margin of error also increases. Because margin of error
= ±Critical value * Std error
= ±Critical value * Std dev/sqrt n
Hence we find that whenever std deviation increases the margin of error increases, for the same level of confidence.
b) Whenever confidence level increases, critical value increases and as a result margin of error increases. Hence by reducing from 95% to 90% confidence interval would be reduced. True
c) Instead of changing conf level, increasing sample size would give more reliale and accurate results.
