Find probability using normal distribution
WebJan 20, 2024 Ā· To find the area between two positive z scores takes a couple of steps. First use the standard normal distribution table to look up the areas that go with the two z scores. Next subtract the smaller area from the larger area. For example, to find the area between z1 = .45 and z2 = 2.13, start with the standard normal table. WebStep 1: Sketch a normal distribution with a mean of \mu=150\,\text {cm} Ī¼ = 150cm and a standard deviation of \sigma=30\,\text {cm} Ļ = 30cm. Step 2: The diameter of 120\,\text ā¦

WebSep 9, 2024 Ā· Using the standard normal distribution table, we can confirm that a normally distributed random variable Z Z, with a mean equal to 0 and variance equal to 1, is less than or equal to z z, i.e., P (Zā¤ z) P ( Z ā¤ z). However, the table does this only when we have positive values of z z. WebThe discrepancy between the estimated probability using a normal distribution and the probability of the original binomial distribution is apparent. The criteria for using a normal distribution to estimate a binomial thus addresses this problem by requiring BOTH np AND n(1 ā p) are greater than five. Again, this is a rule of thumb, but is ...
