Given the following 2 sets of experimental data find the sample mean, sample standard deviation, and sample variance using formulas shown in class. Then, find a histogram for the range of 0.6 to 2.4 with intervals of width 0.2. Finally, plot a normal distribution with the calculated mean and standard deviation. Hint: You must start by putting the two data sets into a single vector. datal (0.9 1.32 1.96 1.85 2.29 1.42 1.35 147 1.74 1.82 1.3 147 192) data2...

A) mean B)Standard Deviation C) Q-test D)Accuracy - Keeping or rejecting the 52 mg measurement (depending on the results of the Q-test), calculate the mean of the modified data set. (Report answer to 1 decimal place and with NO units.) - Calculate the estimated standard deviation of the modified data set. (Report to 1 decimal place and with NO units.)
1. X has a normal distribution with the given mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.) μ = 41, σ = 20, find P(35 ≤ X ≤ 42) 2. Find the probability that a normal variable takes on values within 0.9 standard deviations of its mean. (Round your decimal to four decimal places.) 3. Suppose X is a normal random variable with mean μ = 100 and standard deviation σ = 10....
