**Title: Probability Analysis Based on Gallup Poll Data****Introduction**Based on a 2022 Gallup poll, approximately 40% of people consider economic problems the most important issue in the nation. In this exercise, we will analyze a random sample of 40 people to explore probabilities related to this topic.**Problems and Solutions****a. Probability Calculation**- **Task**: Compute the probability that exactly 10 persons consider economic problems as a top domestic issue. Show your work.**b. Using Excel for Probability Distribution**- **Task**: Use the Excel function "BINOM.DIST" to get a printout of the probability distribution. This can be done by following the instructions found on page 66 of the course packet and pages 269–270 of your textbook.**c. Probability of More Than 15 People**- **Task**: Use the printout from part b to calculate the probability that more than 15 persons consider economic problems as a top domestic issue.**d. Expected Number of People**- **Task**: Calculate the expected number of people who consider economic problems as a top domestic issue.**e. Variance and Standard Deviation**- **Task**: Determine the variance and the standard deviation of the distribution.**Conclusion**This exercise uses real-world data to explore statistical concepts such as probability calculations, expected values, and measures of dispersion using practical tools like Excel.
