e are given the logarithmic function fx) = In(/x + 6). We note that this function is of the form In(g(x)), where g(x) = /x + 6. ecall that since g(x) = Vx + 6 is a differentiable function, then _[In(g(x))] = 9. Applying this rule gives the following result. g(x) Ex) = dx Vx + 6

A parent downloads an app that allows him to monitor the amount of screen time his child is using on the phone. The child claims that she is only using 1 hour per day on the phone on average, but the app, over the course of 47 days, finds that the child used an average of 1.2 hours per day. The parent wants to know if the child is using an average of 1 hour per day for all days of use. a) The 1.2 is a/an: variable population parameter sample statistic observational unit b) The sample size is: 1 47 1.2 c) Each day is a/an: population parameter observational unit variable sample statistic
