You intend to estimate a population mean µ with the following sample. 89.9 80.8 79.2 39.7 40.5 44.3 75.4 42.2 57.2 You believe the population is normally distributed. Find the 99.5% confidence interval. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place). 99.5% C.I. = | Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made p…
