Question 5 The null hypothesis, denoted by Ho, represents the status quo and involves stating the belief that the population parameter is s (less than or equal to), = , or 2 (greater than or equal to) a specific value. The alternative hypothesis, denoted by H,, represents the opposite of the null hypothesis and is believed to be Rev Q&A true if the null hypothesis is found to be false. Note that the hypothesis test is to determine if a relationship 34 O Question 6 exists between the independent variable and the dependent variable. 35 36 38 Print Continue 39 Continue 40 Help me solve this VIGW all CACITINIC UCL IIIVIG IIGIN - VIcal all Check answer Ready data-9_24_2022....xIsx data-9_24 2022....xIsx ~ Show All + 100%Chrome File Edit View History Bookmarks Profiles Tab Window Help D@27% Sat 1:25 AM Q + Share Comments coursehero.com/dashboard/questions rih G Update Do Homework - Chapter 15 Homework 2 mylab.pearson.com/Student/PlayerHomework.aspx?homeworkld=628935469&questionld=3&flushed=false&cld=7023756¢erwin=yes nalysis Data Solve From Tools Analysis Recel QMB3200 Business Statistics, Fall 2022 mod 1 - DeSpain Alex George 09/24/22 1:25 AM V w X Y Z AA HW Score: 10 1% 4 44 of 44 E Homework: Ch Homework View an example | 4 parts remaining X Save Consider the following set of dependent and independent variables.

For a two-tail test, if t is less than the left (lower) critical value or greater than the right (upper) critical value, reject the null hypothesis. Otherwise, do not reject the null Proje hypothesis. Peer Question 4 Use the information from the previous steps to determine if the relationship between x2 and y is statistically com significant. Question 5 c. Interpret the p-value for each independent variable. The p-value represents the probability of obtaining a t-test statistic at least as extreme as the one selected for Rev Q&A the hypothesis test, assuming the null hypothesis is true. For a two-tail test, the p-value is equal to twice the 34 O Question 6 area in either extreme. 35 36 38 Print Continue 39 Continue 40 Help me solve this VIGW all CACITINIC UCL IIIVIG IIGIN - Check answer Ready data-9_24_2022....xIsx data-9_24 2022....xIsx ~ Show All + 100%
