a) What would the value of the test statistic be? Round to three decimal places.

b) What would be the critical value if ?=3%? Round to three decimal places.

c) What would be the conclusion in context?

There (is/ is not) enough evidence to conclude that anxiety is higher for real snakes than for pictures

Is ophidiophobia (fear of snakes) specific to real snakes or will pictures of snakes evoke similar levels of anxiety? Twelve ophiophobes were asked to play with a giant snake (named Steve) with big fangs and an evil look in its eyes, and at a different point in time were shown only pictures of the same big snake. The participants' anxiety was measured in each case. Do a t-test to see whether anxiety is higher for real snakes than for pictures. What would be the correct null and alternative hypothesis? You may assume that to calculate the differences, I did Real Anxiety - Picture Anxiety. a. Ho: a 20 HA: Ha 0 O C Od Oa Ob
