Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of thế same simple random sample and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test for a difference between the measurements from the two arms. What can be concluded? 140 141 136 133 Right arm Left arm 143 180 174 192 140 144 In this example, µg is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the measurement fr the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: Hd = 0 H4: Ha <0 O B. Ho: Ha 0 H: H =0 OC. Ho: Ha#0 H: Hg>0 O D. Ho: Hd = 0 H: Hg #0 Identify the test statistic. t3= (Round to two decimal places as needed.) Identify the P-value. P-value = (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value is V than the significance level, V the null hypothesis. There V sufficient evidence to support the claim of a difference in measurements between the two arms.
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.
