Calculate test statistic Find critical value
What are the hypotheses for the t test? Find the test statistic. Find the critical value(s) What is the correct conclusion of the hypothesis? A researcher randomly selects 6 fathers who have adult sons and records the fathers' and sons' heights to obtain the data shown in the table below. Test the claim that sons are taller than their fathers at the o-0.10 level of significance. The normal probability plot and boxplot indicate that the differences are approximately normally distributed...

Charts • CVs for Normal Distribution .t-chart • Chi Square Chart Claim: > 15 Other Information: unknown, n = 10 Level of significance: a 0.05 Critical Value(s): Claim: p=0.54 level of significance: a = 0.10 Critical Value(s): Claim: o = 200 Other information: n=21 Level of significance...
For the folowing claim, find the null and alternative hypotheses, test statistic, critical value, and draw a conclusion. Assume that a simple random sample has been selected from a normally distributed population. Answer parts a-d. Claim: The mean IQ score of statistics professors is less than 119. Sample data: n 11, x 117, s 14. The significance level is ?-005 Click the icon to view a table of critical t-values. a. Choose the correct null hypothesis (Ho) and altenative hypothesis...
What is the critical value?? The test statistic of z = -2.04 is obtained when testing the claim that p<0.32. a. Using a significance level of a = 0.01, find the critical value(s). b. Should we reject Ho or should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. The critical value(s) is/are z = (Round to two decimal...
Excel can be used to find the critical value for an F distribution for a given significance level. For example, to find the critical value (the value above which you would reject the null hypothesis) for ?=0.05 with dfbetween=3and dfwithin=3, enter =FINV(0.05,3,36) Enter this into Excel to confirm you obtain the value 2.866. You conduct a one-factor ANOVA with 3 groups and 7 subjects in each group (a balanced design). Use Excel to find the critical values for ?=0.02 and...
Google Sheets can be used to find the critical value for an F distribution for a given significance level. For example, to find the critical value (the value above which you would reject the null hypothesis) for α=0.05α=0.05 with dfbetween=3dfbetween=3 and dfwithin=44dfwithin=44, enter =FINV(0.05,3,44) Enter this into Google Sheets to confirm you obtain the value 2.816. You conduct a one-factor ANOVA with 7 groups and 5 subjects in each group (a balanced design). Use Google Sheets to find the critical...
Find the critical value(s) that would be used in a hypothesis test of the following claim. Claim: "The percentage of Michigan residents who oppose a proposed increase in sales tax to pay for road repairs is not 50%." A random sample of 725 Michigan residents was collected, and it produced a test statistic of z = -3.58. A significance level of α = 0.02 is to be used. a. ±2.05 b. ±2.334 c. ±2.586 d. ±2.33
