Consider a binomial experiment for $n=20, p=.05 .$ Use Table 1. Appendix 3, to calculate the binomial probabilities for $Y=0,1,2,3,$ and $4 .$ Calculate the same probabilities by using the Poisson approximation with $\lambda=n p .$ Compare.

Question number five Giving hypothesis of difference of preparations for two independent populations X one and X two with anyone is the sample size of the first sample into the dissemble size of the second sample. All one is a simple the number of success of the first sample, and all too, is the number of successes of the second sample. Uphold preparation preparation is a total number of success is divided by the total assembled soils, so B ball you couldn't old one plus or two over anyone close in two, and this will be the result of this question.

We know that the X distribution or the distribution of random variable X must be normal. In order to use a chi square test variants on the X distribution. Given a sample, what methods are available to determine whether or not a distribution X is normal. If you want to test the variance of of X. But you don't know anything about its distribution and you test its normality. This question is sensing your understanding of the requirements to utilize the chi square tested experience. In particular, it's testing our knowledge of the fact that there are different ways to evaluate the normality of a distribution given what we previously learned in the directory assistance. So remember that we can assess normality with plots. So one way is to assessment really within normal probability plot in a box plot. You can also use other visuals such as history grams Yeah. And like in order to evaluate normality, sir, another way that you can determine normality is to use a goodness of fit test or related hypothesis test. There are tests which are able to evaluate the goodness a bit of a normal distribution to a particular variable given a sample data or given the population data. So therefore, with one of these two tests, we can easily evaluate whether or not the axis normal to evaluate if we can use the chi square distribution or rather, the chi squared test the variance in order to solve.

In question number seven. Given that be equal to a point for four and then equal to 200 it's appropriate to approximate the binomial distribution by the Council of the Distribution F and is greater than or equal 100. And on P is this than 10. So 200 is greater than or equal 100. So m p equal to 205.44 equal to eight. This done 10 so formula. What so capability is for peace one. X equal to K if you to loved up Our came by e our negative London over factories ish in case which London is a product off the sample size. And instead of a planned the probability successes p Solando equal to N P equal to 200 by a point before equal to eight. So evaluate at Kay equal to eight so p when Mexico to eight equal to 848 Boy, be power Negative faith over characterization eight Well approximately equal to all point 13 96 equal to 13.96%.

This problem, we're told that the number of customers arriving per hour is assumed to follow a Poisson distribution with a mean of lambda the seventh. We're talking about two hour period. So, so we're talking about two hour periods. That means that the number of expected customers was actually 14. So this means that with the post in distribution, the probability of X is either the negative 14 times 14 of the acts over ex factory at the end, just following a Poisson distribution. Now, here in this problem, we want to find a couple of different probabilities on a We want to find the probability that more than 10 customers will arrive in a 10 hour period. So the probability that X is greater than 10, there's one minus the probability that is less than or april attempt, which is one minus the sum from X. 0 to 10 will be to the negative 14th. 14 of the act over X factor. We just use our complement rule here in order to take one minus that. And then now to evaluate this, we're going to plug in every X. Value from zero to tim. What can either use a table to do this graphing calculator to do this or which have actually put them all in? Whichever method? Well give us 0.82 43 for our final answer on me. We want to determine what the main number of arrivals during the two hour period is. As we discussed, we have our land value being 14 because we have a two hour period and that's our meat and so we have a mean of 14.
