Leon wants to estimate the proportion of the seniors at his high school who like to watch football. He interviews a simple random sample of 50 of the 200 seniors on campus. He finds that 32 like to watch football. Is the random condition for finding confidence intervals met? Explain.
Yes, the random condition for finding confidence intervals is met because np = 32 and n(1 − p) = 18, both of which are greater than 10.
Yes, the random condition for finding confidence intervals is met because the sample size is greater than 30.
No, the random condition for finding confidence intervals is not met because np = 32 and n(1 − p) = 18, both of which are less than 100.
No, the random condition for finding confidence intervals is not met because the sample is not at least 50% of the population.
Yes, the random condition for finding confidence intervals is met because the sample is a simple random sample.

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
