COVID-19 vaccination is important to help stop the COVID-19 pandemic. A survey conducted showed that only 15% of the Muara community disagree with the COVID-19 vaccination program. Twenty people from the Muara community were randomly selected. Let Y be the number of people who disagree with the newly COVID-19 vaccination program among the selected Muara community. 1)state the distribution of Y and give its probability distribution function. 2)what is the probability that all of them agree with the vaccination program? 3)calculate the probability of Y not exceeding its mean

)The average number of pounds of red meat a person consumes each year is 196 with astandard deviation of 22 pounds (Source: American Dietetic Association). If a sample of 50individuals is randomly selected, find the probability that the mean of the sample will beless than 200 pounds
Due COVID-19 pandemic, all institutions and students in United State used special platforms to continue their interactive education online, mainly: MS Teams and Zoom. In a statistical survey, it was found that 20% of the primary school students use MS Teams, and 25% of the university students use Zoom. If one student was selected at random, and he was a Zoom user, what is the probability that he is a university student? given that 10% of the students in United State are university students.

In a study on the dissemination of fake news, users of a social network were classified into two groups: ''susceptible'' and 'not susceptible'. Suppose that in the social network considered in the study, the probability of a randomly drawn user being susceptible is 0.5. In this social network, the probability of a user propagating fake news is 0.9, if the user is "susceptible". Otherwise, this probability is 0.15. Based on this data, calculate the probability: Note: All final answers must be rounded to 4 decimal places of approximation, but do not do any rounding in the middle stages of the solution. a) the probability of a randomly drawn social network user propagating fake news. b) the conditional probability that a randomly drawn user is susceptible, given that he propagates fake news. c) the conditional probability that the randomly drawn user is "not susceptible", since he does not propagate fake news.

Are people born in certain seasons more likely to be allergic to dust mites? Research suggests this might be true. The table below gives the birth seasons of 500 randomly selected people who are allergic to dust mites, along with the proportion of births in the general population for each season. Do these data provide convincing evidence that the distribution of birth season is different for people who suffer from this allergy? Number of allergy sufferers Proportion of births in general population Birth Season Winter 117 0.30 Spring 105 0.22 Summer 145 0.24 Fall 133 0.24
Suppose that we have disjoint normal populations A and B with equal population variances. Suppose we plan a sample of size 4 from from population A and a sample of size 9 from population B which we will pool to form the pooled variance. If you know the population variances are both in fact equal to 6, what is the probability that the pooled variance of the two samples will turn out to be less than 8 given your information?
