- Find the probability of each event. Drawing two aces from a card deck without replacing the card after the first drawarrow_forwardQuestion 7 The suicide rate in a certain state is 1 suicide per 100,000 residents per month. There are 400,000 residents in a certain city within this state. a) Use a suitable approximation to find the probability that there will be 3 or more suicides in the city in a given month. Assume independence between residents of the city. b) Find the probability that there will be at least 2 months during the year with 3 or more suicides in the city. Assume independence between months of the year.arrow_forward(Topic 12) The following data is based upon the results from the *Granite State Poll made available on October 19th, 2020. The poll asked respondents about how stressed they were on a scale of 1 through 10 (10 being most stressed) regarding certain events in 2020. According to the survey, 43% of the 930 respondents (New Hampshire residents) answered 7 or greater when asked how stressed they were about Covid-19. Use this information to answer each part below. (a) Write out the formula you should use and calculate the 95% margin of error for the proportion of all New Hampshire residents that would answer a 7 or greater for their stress level about Covid-19. (b) Find the 95% confidence interval for the proportion of all New Hampshire residents that would answer a 7 or greater for their stress level about Covid-19. (c) Based upon your previous results, are you 95% confident that the majority of New Hampshire residents would answer 7 or greater for their stress level about Covid-19.arrow_forward
- QUESTION 11 A gambler belives that he has learned to predict the color of a card befroe it is drawn from the deck. In order to test this, he predicts a color, draws a card from a fresh deck of 52 cards and observes its color, replaces the card, and then shuffles. He repeats this process 19 times, and finds that he got 15 predictions incorrect. Using a sign test, test the hypothesis that the gambler is getting fewer predictions inccorect than one would expect due to chance. sig = ? QUESTION 12 Click Save and Submit to save and submit.
