A large population of college students were surveyed regarding their uses of technology. One question on the survey was: "How many different social media platforms do you use on a regular basis?" The distribution of responses to this question is Normal, with a mean μ= 3.9 and standard deviation σ= 1.1. What is the percentage of students in this population who use more than 5 social media platforms on a regular business. A percentile is a collection of observations that are greater than some percentage of all observations. For example, an observation is in the 90th percentile if at least 90% of all other observations are less than it. In a Normal distribution, what is the smallest z-score of an individual in the 90th percentile? Give your answer to two decimal places.
