A sample of size n = 300 is taken from a population which may be classified into 4 different categories. Let p k denote the proportion in the population who belong to category k, k = 1, . . . , 4. If the null hypothesis is: H 0 : p1 = 0.2 p2 = 0.3 p3 = 0.1 p4 =? and the observed counts are n1 = 62 n2 = 96 n3 = 35 n4 =? deduce the values...
The authors of a paper studied a random sample of 346 Twitter users. For each Twitter user in the sample, the tweets sent during a particular time period were analyzed and the Twitter user was classified into one of the following categories based on the type of messages they usually sent. Category Description IS Information sharing OC Opinions and complaints RT Random thoughts ME Me now (what I am doing now) O Other The accompanying table gives the observed counts...
The categories of a categorical variable are given along with the observed counts from a sample. The expected counts from a null hypothesis are given in parentheses. Compute the χ2-test statistic, and use the χ2-distribution to find the p-value of the test.

A sample of size n=35 was used to conduct a test of the null hypothesis H0: μ = 500. The value of the test statistic is 1.48. What is the p-value of the test statistic? Include 4 decimal places in your answer.
for the given binomial sample size and null hypothesized value of p0 determine whether the sample size is large enough to use the normal approximation methodology to conduct a test of the null hypothesis h0:p=p0 n=600, p0=0.02 n=90, p0=0.3 n=50, p0=0.8

Consider a multinomial experiment with n = 260 and k = 4. The null hypothesis to be tested is H0: p1 = p2 = p3 = p4 = 0.25. The observed frequencies resulting from the experiment are: (You may find it useful to reference the appropriate table: chi-square table or F table) Category 1 2 3 4 Frequency 73 44 75 68 a. Choose the appropriate alternative hypothesis. All population proportions differ from 0.25. Not all population proportions are equal...
z-test a sample for the null hypothesis using α = 0.05 as our threshold a) Given a population with mean of 550 and variance of 100, what would be minimum sample mean to reject the null hypothesis if our sample size is 20? b) Given a population with mean of 550 and variance of 100, what would be maximum sample mean to reject the null hypothesis if our sample size is 20? c) Let’s assume the same population mean and...
