9. In 2016 an online poll was conducted regarding the results of the 2016 NBA All-Star Dunk Contest. The poll asked 100,000 people, "Who [do you think] won the dunk contest?". The results are shown in the relative frequency table below Percentage 55% Response Aaron Gordon Zach Lavine 45% Suppose we would like to estimate the proportion of all NBA fans who thought Aaron Gordon won the dunk contest. What is the value of the point estimate a. for our 95% confidence interval? What is the margin of error for our 95% confidence interval? (Use the formula to compute it). Round your answer to three decimal places. b. "sing your answers to parts (a) and (b), find a 95% confidence interval estimating the proportion of all NBA fans who thought Aaron Gordon won the dunk C. contest.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
