B. Answer what is asked from each number using proper probability notation and units wherever possible. 1. What is the probability that a randomly selected respondent is male (let M represent the random variable)? 2. What is the probability that a certain adult in the community selected at random received at least 2 vaccination shots? 3. What is the probability that 40 randomly selected adult in the community received an average of at least 2 vaccination shots? 4. What sample size of the adults in the community should be taken so that the probability that their mean vaccination shot is less than 2 is 78%? 5. If there are 987 adults (18 years old and above) in the community, how may would be expected to have a vaccination shot between 1 and 2? 6. The researchers would like to conclude that the adult community is hesitant to the COVID 19 vaccination if 87% of the adult community received at most of 1 vaccination shot. Is the adult community hesitant to the COVID 19 vaccination? 7. According to the Department of Health, senior citizens have a mean vaccination shot is 1.36 with a standard deviation of 1.2. The researchers would like to conclude that the senior citizens in the community is hesitant to the COVID 19 vaccination if the probability that the senior citizens in the community received an average of 1 vaccination shot is at least 80%. Are the senior citizens in the community hesitant to the COVID 19 vaccination?
