Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

What is the median?
ou are doing a problem where you have a negative z-score, and you have to look up the proportion of the shaded area in the tail beyond that z-score; in other words, you are shading to the left from your z-score, and looking for the proportion that you shaded. Four “proportions” are given below. Which one is the ONLY one that could potentially be the number you are looking for? (Hint: Think about what you know about proportions: What kind of number are they? And what things can they represent?) Group of answer choices p = 0.3800 p = -0.1500 p = 1.1500 p = 0.5635

Macmillan Learning An extensive study in Antarctica concluded that the mean height of adult emperor penguins in the wild is 44.5 in. Cassandra believes that captive emperor penguins have a greater mean height due to better nutrition. To test this idea, she decides to conduct a one-sample t-test to see if the mean height of captive emperor penguins is greater than 44.5 in. She selects a simple random sample of 26 penguins from different zoos around the country and has each penguin measured. The summary statistics of the sample are given below. Sample size n = 26 Sample mean x = 45.6 in Sample standard deviation s = 4.3 in The heights of emperor penguins are normally distributed, and there are no outliers in the sample. Construct the null and alternative hypothesis for the appropriate one-sample t-test for the mean height of captive emperor penguins. Ho: H₁: =

HOW Do I solve this in EXCEL In 2016, the Better Business Bureau (BBB) settled 80% of complaints they received in the US. Suppose you have been hired by the BBB to investigate the complains they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the BBB is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.8, the same as the overall proportion of complaints settled in 2016. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of pbar. Based on a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion? Suppose you select a sample of 450 complaints involving new car dealers. Show the sampling distribution of pbar. Based on the smaller sample of only 450 complaints, what is the probability that the sample proportion will be within…
