- Find the average, variance and the standard deviation for the following: 1.23, 1.24, 1.18, 1.19, 1.26, 1.21, 1.22, 1.25, 1.20, 1.27, 1.28Question 6 5 p A standardized exam is known to be normally distributed with a mean score of 82 and a standard deviation of 6.58 in the examination. (Hint: so this means you can convert individual exam scores to z-scores and calculate percentile rank). One student named Amy has an exam score of 78. For Amy's score, compute the corresponding z score. Make sure to round the z-score to the nearest hundredth place (Hint if the z-score is 0.3615, then you round it to 0.36).A student collects a series of six groundwater samples from a well. She measures the dissolved oxygen concentration in six of these. Her observations in mg/L are: 8.8, 7.1, 7.2, 8.2, 7.6, 8.6. Plot a graph based on the given values above. Find the mean of the different samples collected and Find the variance. Kindly encode your answers and complete solutions. Thank you!
