Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.10 significance level to test for a difference between the measurements from the two arms. What can be concluded? 142 137 130 Right arm Left arm 132 127 174 172 184 137 147 O A. Ho: Ha =0 O B. Ho: Ha #0 H: Ha =0 O D. Ho: Ha 0 OC. Ho: Ha = 0 H1: Hd <0 H1: Hd>0 Identify the test statistic. t=](Round to two decimal places as needed.) Identify the P-value. P-value =O (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test?
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.
