Use the Student's t-distribution calculator to calculate the p-value. Calculator t = : P(T≤t) = A sample of 20 from a population produced a mean of 66.3 and a standard deviation of 9.5. A sample of 25 from another population produced a mean of 60.4 and a standard deviation of 12.1. Assume that the two populations are normally distributed and the standard deviations of the two populations are equal. The null hypothesis is that the two population means are equal, while the alternative hypothesis is that the two population means are different. The significance level is 5%. What is the p-value for this test, rounded to three decimal places? Use the Student's t-distribution calculator to calculate the p-value.
