Find normal distribution

WebFind the probability that a randomly selected bag contains less than 178\,\text {g} 178g of candy. Let's solve this problem by breaking it into smaller pieces. Problem A (Example 1) Find the mean of T T. \mu_T= μT = grams. Problem B (Example 1) Find the standard deviation of T T. \sigma_T= σT = grams. Problem C (Example 1) WebThe standard deviation is 0.15m, so: 0.45m / 0.15m = 3 standard deviations. So to convert a value to a Standard Score ("z-score"): first subtract the mean, then divide by the Standard Deviation. And doing that is called …
