You wish to test the following claim (HaHa) at a significance level of α=0.05α=0.05. Ho:μ1=μ2Ho:μ1=μ2 Ha:μ1>μ2Ha:μ1>μ2You believe both populations are normally distributed, but you do not know the standard deviations for either. However, you also have no reason to believe the variances of the two populations are not equal. You obtain a sample of size n1=19n1=19 with a mean of M1=65.2M1=65.2 and a standard deviation of SD1=18.8SD1=18.8 from the first population. You obtain a sample of size n2=26n2=26 with a mean of M2=51.3M2=51.3 and a standard deviation of SD2=10.8SD2=10.8 from the second population.What is the p-value for this test? For this calculation, use the conservative under-estimate for the degrees of freedom as mentioned in the textbook. (Report answer accurate to four decimal places.)p-value = The p-value is... less than (or equal to) αα This test statistic leads to a decision to... reject the null As such, the final conclusion is that... The sample data support the claim that the first population mean is greater than the second population mean. WHAT IS THE P-VALUE?

You believe both populations are
What is the p-value for this test? For this calculation, use the conservative under-estimate for the degrees of freedom as mentioned in the textbook. (Report answer accurate to four decimal places.)
p-value =
The p-value is...
- less than (or equal to) αα
This test statistic leads to a decision to...
- reject the null
As such, the final conclusion is that...
- The sample data support the claim that the first population mean is greater than the second population mean.
