Suppose you want to estimate the percentage of videos on YouTube that are cat videos. It is impossible for you to watch all the videos on YouTube so you use a random video picker to select 1000 videos for you. You find that 2 % of these videos are cat videos. Determine which of the following is an observation, a variable, sample statistics or a population parameter.
⦁   The percentage of all videos on YouTube that are cat videos
⦁   2% of cat videos on YouTube
⦁   A video in your sample
⦁   Whether or not a video is a cat video

    For each question mark TRUE or FALSE, and write a justification for your answer. Remember that a parameter applies to a population whereas a statistics applies to a sample. 1. In a study of all 2857 employees at a college, it is found that 45% own a vehicle. TRUE OR FALSE: The number 45% is a parameter. 2. In a survey, one hundred college students are asked how many hours per week they spend on the Internet. TRUE OR FALSE:...

    A survey of 2,350 adults reported that 53% watch news videos. Suppose that you take a sample of 500 adults. If the population proportion of adults who watch news videos is 0.53, what is the probability that fewer than half in your sample will watch news videos? The probability is ? that fewer than half of the adults in the sample will watch news videos. (Round your answer to four decimal places)

    2. Suppose the mean length of a YouTube video is 7.45 minutes. Marcella wants to know if YouTube videos are becoming shorter on average. She randomly chooses 30 YouTube videos made in the last month, and computes their mean length as 6.87 minutes and their standard deviation as 2.4 minutes. Can Marcella conclude that YouTube videos have become shorter in the last month? Use a significance level of 0.05. Note that since Marcella has a sample size of geq30, she...

    Suppose you monitor quality assurance for a local hospital and want to estimate the average length of stay (LOS) at your hospital. You take a random sample of 30 patients and find that the average LOS is 3.8 days with a sample standard deviation of 1.2 days. What is the 95% confidence interval for the population average length of stay? Select one: (3.43, 4.17) (3.35, 4.25) (3.20, 4.40) (3.61, 3.82) none of these are correct

    PROBLEM 1 Suppose you wish to estimate the total number of physicians in the United States. County records of all counties contain the number of physicians in each county. The records furthermore contain information on the county size and the number of residents. A census also determined that in 1993 there were 255,077,536 residents in 3141 counties in the US. The total land area is 3,536,278 square miles. Suppose a random sample of 100 counties #of physicians in county i,...
