PLEASE ANSWER ALL PARTS The mean number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of four English courses with a standard deviation of 0.8. The females took an average of five English courses with a standard deviation of 1.1. Are the means statistically the same? (Use...

Spring Constants & Periods By varying the mass placed on a spring, the period of oscillation can be changed. When multiple data sets are collected and plotted, the spring constant can be determined. Before data was collected, the minimum and maximum masses were determined by visually watching the harmonic motion. For the minimum, a mass was chosen such that the resulting simple harmonic motion had an appreciable amplitude without significant dampening over ten periods. For the maximum, the mass was...

Allen's hummingbird (Selasphorus sasin) has been studied by zoologist Bill Alther.† Suppose a small group of 18 Allen's hummingbirds has been under study in Arizona. The average weight for these birds is x = 3.15 grams. Based on previous studies, we can assume that the weights of Allen's hummingbirds have a normal distribution, with σ = 0.36 gram. (a) Find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of...
