Problem 11

Consider a test of H0 : 100 versus H1 : > 100. Suppose that a sample of size 20 has a sample mean of X = 105. Determine the p-value of this outcome if the population standard deviation is known to equal (a) 5; (b) 10; (c) 15.

Step-by-Step Solution:
Step 1 of 3

Simple Linear Regression  Analyzing relationship between 2 variables  X= hours studied Y=test score  Response variable (y)= dependent variable  Explanatory variable (x)= independent variable o Helper o Helps estimate mean of y’s  Scatterplot used to identify o Patterns/ relationships o Outliers  What regression line gives you o Line of means for y population o Prediction of the mean o Value of the regression equation is the “least squares” estimate of the mean of that y subpopulation  Include units!! sample correlation coefficient, r  Measures the strength of the LINEAR association between 2 quantitative variables  P= population corr
