Description

  1. use the appropriate descriptive statistics from W2 Assignment 2.
  2. Assuming that the sample statistics you computed are exactly equivalent to the corresponding population parameters, identify the following:
    • What score on Recall1 would correspond to an extremely high score?
    • What score on Recall1 would correspond to an extremely low score?"

To find these hypothetical scores, solve for X (your raw score) using the following formula:

X = (±z)(sd) + M, where

z = The z-score cutoff for 5 percent in the tail (±1.645)

sd = Your sample standard deviation

M = Your sample mean

  1. Use Minitab to compute z-scores for Recall1. Complete the table, indicating the appropriate z-scores corresponding to each of the participants whose score is given.

There was a total of 72 random participants in a study conducted involving stress levels while writing a final exam. Of the 72 participants, there were 2 groups: 36 females and 36 males. Tally Sex Count F 36 M 36 N= 72 Among the 72 participants, their ages ranged from 18 to 49 years, with a mean age of 27.7500 and a SD of 7.8449.
