solve the following ### Probability and Opinion Polls on TranquilizersResearchers at a reputable university and a reputable health organization claim that approximately 74% of people believe "tranquilizers work very well to make a person more calm and relaxed." Of the next 85 people interviewed, what is the probability that:(a) At least 53 are of this opinion?(b) At most 61 are of this opinion?**Instructions:**- To calculate these probabilities, you may need to refer to the standard normal distribution tables.- Click the links below to access the necessary tables: - [Click here to view page 1 of the standard normal distribution table.](#) - [Click here to view page 2 of the standard normal distribution table.](#)**Calculations:**1. **(a) The probability is:** ⬜ (Round to four decimal places as needed.)2. **(b) The probability is:** ⬜ (Round to four decimal places as needed.)### How to Interpret the Graphs and DiagramsThe standard normal distribution table (Z-table) provides the area (or probability) to the left of a given Z-score in a standard normal distribution. You can use these tables to find the probability corresponding to a particular Z-score value. - **Page 1 of the standard normal distribution table** generally includes Z-scores ranging from negative infinity up to a Z-score of zero.- **Page 2 of the standard normal distribution table** typically covers Z-scores from zero to positive infinity.You will use these tables to find the cumulative probabilities, which will help you in determining the overall probabilities for events (a) and (b).**Example Calculation Steps:**1. Calculate the mean (μ) and standard deviation (σ) for the given scenario.2. Convert the specific count values (53 and 61) into Z-scores.3. Use the Z-scores to find the corresponding probabilities from the standard normal distribution tables.4. Round the results to four decimal places as requested.

Given that,p=74% =0.741-p=1- 0.74 = 0.26n = 85
