Overall, the amount of days attended {per year] is normally distributed around 2?5 days with a standard deviation of 25 days. What's the probability that the mean number of days will be between 200 and 310? What percentile does an attendance of 2?5 days rank at? What percentile does an attendance of 285 days rank at? The parents with children at or below the 10%ile of number of days need to bring an explanatory note. What will be the threshold of 19%? How likely [what is the probability] is it to have the number of days attended above 250? How likely [what is the probability] is it to have the number of days emactlyr 250? How likely [what is the probability] is it that a child will attend the daycare between 285 and 293 days? Children that are in the top 8% of attendance will receive a ticket to see the Bubbleclown. What is the minimum number of days of attendance _r!_ order to receive such a ticket? If 9 children [9 = size of the sample] selected randomly attend the Daycare, what's the likelihood that their mean number of attended days will be within 20 days of the population mean
