Answer the questions in the previous problem when the population is a mixture of two normal distributions. Specifically, suppose each observation has a 65% chance of coming from a normal distribution with a mean of 100 and a standard deviation of 20 ...

We have presented a new unified approach to model the dynamics of both the sum and difference of two correlated lognormal stochastic variables. By the Lie-Trotter operator splitting method, both the sum and difference are shown to follow a shifted lognormal stochastic process, and approximate prob...
Verify approximate satisfaction of the assumptions: (a) normal distributions and (b) equal variances in the original data of the k groups 3. Choose the error probability α, such as 5%, you are willing to accept and find the associated critical value of F, named F0, in Table V for k...
In this paper, the Type IV Pearson distribution is proposed to approximate the distribution of the sum of lognormal random variables, and the parameters of the Type IV Pearson distribution are derived through matching the mean, variance, skewness and kurtosis of the two distributions. Numerical sim...

Looking at the dot plots for the two groups,several questions come to mind.Firstly,do the data come from Normal distributions?Unfortunately we can’t say much about the distributions as the samples are too small.However there does not seem to be any clear lack of symmetry.Secondly,are the ...

To do that, we first create an array with two rows and 3 columns. We set the last column to np.nan to indicate that we don't know the labels. And we set the rest of the values in the 2D array accordingly.test_classification = np.array([3.0, 4.0, np.nan, 12.0, 18.0, np.nan...
