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?

A. Yes, the random condition for finding confidence intervals is met because npp = 32 and n(1 − pp) = 18, both of which are greater than 10.

B. Yes, the random condition for finding confidence intervals is met because the sample size is greater than 30.

C. 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.

D. No, the random condition for finding confidence intervals is not met because the sample is not at least 50% of the population.

E. Yes, the random condition for finding confidence intervals is met because the sample is a simple random sample.

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
