Find mathematically (and then plot) the posterior distribution for a binomial likelihood with x =5 successes out of n = 10 trials using five different beta prior distributions. Does the prior makea large difference in the outcome? If so when? To answer this question complete the following:(a) Find the mathematical formula for the Likelihood Function, using the information aboveand below.

L(p|x,n) = (n choose x) * p^x * (1-p)^(n-x) where p is the probability of success, x is the number…

Each week Lloyds department store selects a simple random sample of 100 customers in order to learn about the amount spent per shopping trip. The historical data indicates that the population follows a normal distribution. During the most recent week, Lloyd’s surveyed 100 customers (n = 100) and obtained a sample mean of (x ) ̅ = $82. Based on historical data, Lloyd’s now assumes a known value of σ = $20. Calculate the 99% confidence interval

In spite of an unemployment rate of 26% and an economy in crisis, 70% of people in a certain country responded that they were in favor of keeping the euro rather than returning to their original currency. A random sample of 33 people from the country was selected. Use the normal approximation to the binomial distribution to answer parts a through e. a.

This is what it means to be "95% confident" when we create a 95% confidence interval for thepopulation mean: If we take repeated random samples of the same size ? from our population andcalculate all of the sample means and all of the corresponding 95% confidence intervals, we expect__________ of those intervals will contain the true population mean (µ).
