The dot plot shows the number of days from hatching until their first flight for 12 northern spotted owlets. 30 35 40 Days from hatching to first flight. Which of the following is the closest estimate to the.The empirical rule, also referred to as the three-sigma rule or 68-95-99.7 rule, is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ ). In particular, the empirical rule predicts that 68% of all observations ...One, two, three, four, five, six, seven. So seven of the 14 are below six hours. So we could just say seven, if we use this first technique we would have seven of the 14 are below six hours per day, and so that would get us a number of 50%, that six hours is at the 50th percentile.

Apr 16, 2019 · I have to write some code to calculate the 95th percentile from a databaset which is normally distributed. I am easily able to calculate the mean and the standard deviation, which define the distribution. However, from those two values alone, is it possible to determine the x value of the 95th percentile? The mean, median, and mode are three of the most common measures of the center of a distribution (whether it's a binomial distribution, Poisson distribution or any other distribution), also called the central tendency.. Mean, median, and mode definitions: The mean is the average of all numbers.. The median is the "middle" number, where there is an equal number of values less than and greater ...

The question states that the minimum daily intake is 1700 ... workday ssm health The value of z is 0.674. Thus, one must be .674 standard deviations above the mean to be in the 75th percentile. Second, the standard deviation is 5, one must be: (5) (.674) = 3.37. points above the mean. Since the mean is 80, a score of 80 + 3.37 = 83.37 is necessary. Rounding off, a score of 83 is needed to be in the 75th percentile.
