1. Technology required. Data in the table shows the relationship between average number of social network notifications a student receives during one class, x, and average test scores, y. average number of social network notifications, x average test score, y a. According to this data, does the average number of 12 92 26 84 social network notifications 17 87 have any effect on the 43 65 average test score a 51 57 student receives? Use the 29 75 concepts we have learned in unit 4 to justify your 13 83 4 100 answer. 16 86 12 73 25 67 22 77 12 89 8. 91 34 98 b. Use the line of best fit to make a prediction about what the test score will be for a student who receives 70 social media notifications during one class. Is this realistic? Explain your answer.
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.
