Part I) Suppose the researchers collect data with the following summary statistics: Sample size Mean SD Control group 11 4.8 1.12 'Bad economy' group 12 4.99 1.11 Compute the test statistic for the two-sample t-test here, giving your answer to two decimal places. Part 2) The P-value (or p-value) of a test statistic is the probability of observing a value of the test statistic at least as inconsistent with the null hypothesis as the value observed, assuming the null hypothesis is true. Find the P-value of the test statistic you found above, giving your answer to three decimal places.
