Consider the following competing hypotheses and accompanying sample data drawn independently from normally distributed populations. (You may find it useful to reference the appropriate table: z table or ttable) HO: M1 - u2 = 0 HA: Mi - M20 x1 = 73 01 - 11.00 ni = 16 x = 79 02 - 1.68 n2 = 16 a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.) Test statistic a-2. Find the p-value. O 0.01 s pvalue < 0.025 Opvalue < 0.01 Opvalue 0.10 O 0.05 s pvalue < 0.10 O 0.025 s pvalue < 0.05 a-3. Do you reject the null hypothesis at the 10% significance level?
a-2. Find the p-value. O 0.01 s pvalue < 0.025 Opvalue <0.01 Opvalue 0.10 O 0.05 s pvalue < 0.10 O 0.025 s pvalue <0.05 a-3. Do you reject the null hypothesis at the 10% significance level? O No, since the pvalue is more than a No, since the pvalue is less than a. Yes, since the pvalue is more than a Yes, since the pvalue is less than a a-4. Interpret the results at a = 0.10. We cannot conclude that the population means differ. We conclude that the population means differ. O We cannot conclude that population mean 2 is greater than population mean 1. We conclude that population mean 2 is greater than population mean 1.
