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

Transcribed Image Text:

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 b. Ho: Ma 0 HA:Hd = 0 c. Ho:td = 0 HA:Hd 0 d. Ho: a ≤0 HA: Hd > 0 O C Od Oa Ob Is ophidiophobia (fear of snakes) specific to real snakes or will pictures of snakes evoke similar levels of anxiety?
