ACTIVITY NO.IDirections: Analyze the problem below by providing a comprehensive answer from the given question. Write thecomplete solution in SHORT BOND PAPER and show a graph of a standard normal curve.I. The height (in meters) of grade II students in section A, follows a normal distribution with the mean 1.6 and astandard deviation of 0.3. Find the probability that students chosen at random has a height greater than 1.75.2. The scores in the summative test of II- STEM B are normally distributed with a mean of 65 and a standarddeviation of 12. Find the probability that some students got a score below 40.3. The mean score and the standard deviation in the Statistics test are respectively equal to 80 and 2.5, whereas inthe Mathematics test the mean score is 70 and the standard deviation is 2. If Liza got a score of 85 in Statisticsand a score or 75 in Mathematics in which subject is her standing better assuming normality in both subjects?4. Determine the z value for each of the following x values for a normal distribution with mean of 56 and astandard deviation of 7. and determine whether the z-score is below, above or equal to mean.A. 42B. 70C. 45D. 67

This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability. All work must be shown in order to receive any credit. Please upload your completed assignment here.
