The Normal Distribution is meaning when you divide it down the middle, the right hand side is a mirror reflection of the left hand side. O perfectly symmetric positively skewed commonly used negatively skewed

← 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 0.05 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm Left arm 148 174 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 from 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 H₁ Hd #0 OC. Ho Hd #0 H₁-Hd = 0 135 121 137 134 170 190 152 134 Identify the test statistic. (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 than…

Which of the following are true about the normal curve? Check all that apply.   The normal curve is skewed to the right.   The normal curve is unimodal.   The normal curve touches the horizontal axis.   The normal curve is symmetrical

Based on the Histogram describe the distribution of the variable WPM is it symmetric, skewed left, skewed right, bimodal, uniform, or random.

Please give handwritten

Determine wheaten the graph can represent a normal curve, if it cannot explain why ?

Only typing answer Please explain step by step
