51 measured data points have a sample mean of 56.04 and a standard deviation of 3.4. Estimate the range of values for which you would expect 95% of all future measurements to fall (or for a single future measurement to fall within 95% probability). Find a, where the data is expected to fall ±a about the sample mean

A measurement of the acceleration of gravity g is made and the data set is used to calculate a mean and a standard deviation. The mean is 10.00 m/s2, and the standard deviation is 0.67 m/s2. 1. What range of values for g would include about 70% of the data set? What range would include about 95% of the data set? 70% Range: to m/s2. 95% Range: to m/s2. If you have two sets of measurements, and know the mean and standard deviation of...
A sample of 10,000 electrical measurements has a mean of 380 kilovolts and standard deviation = 5 kilovolts. The measurement does not follow any particular distribution. (a). use Tchebysheff's theorem to find the range of measurements [low, high] so that probability will be at least 80% (b). Use Tchebysheff's theorem to find the measurement value that will be greater than at most 5% of the time
10.1 A. Calculate the mean and standard deviation of the following securities’ returns: Year Computroids Inc. Blazers Inc. 1 10% 5% 2 5% 6% 3 –3% 7% 4 12% 8% 5 10% 9% B. Assuming these observations are drawn from a normally distributed probability space, we know that about 68% of values drawn from a normal distribution are within one standard deviation away from the mean or expected return; about 95% of the values are within two standard deviations; and...
Please Solve correctly. For a sample of N=41 measurement, the average and standard deviation are 50 and 2.5 respectively. If an additional measurement is made ,find an estimate at 95% (Explain & show your work) If these measurements are a sample form a larger population ,estimate the mean at 95%.
