Question Help ▼ The following data represent the level of health and the level of education for Education a random sample of 1935 residents. Complete parts (a) and (b) below. Excellent Good Fair Poor Not a H.S. graduate H.S. graduate Some college Bachelor Degree or higher 87 191 119 100 103 188 143 99 99 181 74 110 61 187 88 105 Click the icon to view the Chi-Square table of critical values. (a) Does the sample evidence suggest that level of education and health are independent at the a = 0.05 level of significance? Conduct a P-value hypothesis test. State the hypotheses. Choose the correct answer below. A. Ho: Level of education and health are independent. H: Level of education and health are dependent. O B. Ho: H1 =E, and u2 =E2 and Ha =Ez and H4 =E4 expected. H: At least one mean is different from what O C. Ho: P1 = P2 = P3 H: At least one of the proportions are not equal. Calculate the test statistic. X6 = (Round to three decimal places as needed.)
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.
