********* *********** Give as much information as you can about the P-value of a t test in each of the following situations. (Round your answers to three decimal places.) (a) upper-tailed test, df = 6, t = 2.0 (b) lower-tailed test, df = 10, t = -2.3 ******** (c) lower-tailed test, n = 23, t = -4.3

Solve Part a Suppose X is a normally distributed variable with a mean of 10 and a deviation of 2. Please give a numerical solution for part (a) a. Find p(X<0)

n an independent samples t-test, the researcher is drawing a bar plot for their data and they want to include SE (Standard Error) Error bars. They have an experimental condition (Mean = 5, SE = 1) and a control condition (Mean = 3, SE = 1). The error bars for the experimental condition bar will extend from ______ to _____

Visualizing Statistical Precision Each graph below shows a scatter plot of an outcome (y or w) over x.  The red circles represent the sample means of the two groups.  Both graphs have 50 observations in the 0-group and 50 observations in the 1-group and the axes on both graphs are identical.  The difference between group averages is also the same (group-1 average is 37 higher than group-0).        Below are the results of t-tests for the difference in means for each outcome. The results are in no particular order. Results 1   group-1 mean group-0 mean difference standard error t-stat p-value   182 145 37 5.7 6.49 <0.001               Results 2   group-1 mean group-0 mean difference standard error t-stat p-value   182 145 37 12.1 3.06 0.003   Which results correspond to the difference in means for outcome y? a. Results 1 b. Results 2 c. Not enough information to determine

100) The absolute value the calculated t value for a paired t-test. The critical value you would use if doing a two-tailed test.   The critical value you would use if doing a one-tailed test.  The result of a two-tailed test.  The result of a one-tailed test.

How do I find the population mean (not the sample mean) in order to solve for t? (Second page)
