Assume that the number of cases of COViD-19 per day are normally distributed with a mean of 816 and a standard deviation of 91 on any given day. For parts (a) to (c) enter yor answers in decimal form rounded to 4 decimal places (i.e. 0.0003 instead of 0.03%). (a) What is the probability that on that day there will at most 755 cases? O (b) What is the probability that on that day there will be between 625 and 863 cases? 0 (c) What is the probability that on that day there will be at least 1,080 cases? D (c) What is the number of COVlD-19 cases that is the cut-off for the top 5% of COVID 19 cases? Round answer to the nearest whole number. 0
