5 = 390 so the mean average is 390 mm . to calculate the variance, compute the difference of each from the mean, square it and find then find the average once again. so for this particular case the variance is : = (220 2 + 60 2 + (-230) 2 +30 2 + (-80) 2 )/5 = ...
Related to this Question Suppose X ~ N(2, 6). What value of x has a z-score of three? Calculate the z-value of 80%. Calculate \iint_s f(x, y, z) dS For y = 4 - z^2, \ \ \ \ 0 \leq x, z \leq 8; \ \ \ \ f(x, y, z) = z \iint_s f(x, y, z) dS...
We have also added a BMI calculator that you can use to determine the BMI quickly. You can also calculate the z-score of BMI after reading the article. We get different formulas for calculating BMI because of different units of height and weight. You can get a clear concept about the ...
*This process is made much easier if you use a TI-83 or Excel to calculate the z-score (the “critical value”). See: Critical z value TI 83 Z Score in Excel Hypothesis Testing Examples: Mean (Using TI 83) You can use the TI 83 calculator for hypothesis testing, but the calculator...
6. Calculate the z-score by subtracting the mean from any data point in your list and then dividing that answer by the standard deviation. Using the invNorm Function 1. Press 2ND and then VARS to display the DISTR menu. Select 3 and press ENTER to bring up the invNorm wizard screen. ...
First you need to know more than just the score, you need the actual number of Promoters, Detractors and Neutrals in your sample: #P is the number of promoters #N is the number of Neutrals #D is the number of Detractors. Now we calculate the total respondents: ...
