Can you show me how to find tx? b. Identify the p-value from part a and interpret the result. The p-value is the probability of observing a sample mean at least as extreme as the one selected for the hypothesis test, assuming the null hypothesis is true. For a two-tailed test, the p-value is equal to twice the area in either extreme. Part 13 Use technology to find the area to the left of the test statistic, rounding to three decimal places. Recall that dfequals16. The area to the left of t Subscript x overbarequalsnegative 0.91 is 0.188. Part 14 Multiply this area by 2. 0.188times2equals0.376
