Spider or Picture?		N		Mean	Std. Deviation			Std. Error Mean
Anxiety of the Picture		12		40.00	9.293			2.683
Anxiety of Real Spider		12		47.00	11.029			3.184
			t-test for Equality of Means
			t			df	Sig. (2-tailed)
Anxiety	Equal variances assumed		-1.681			22	.107

Answer 1

Answer Date: 11/04/2019 To test the hypothesis is that the mean of spider phobia level is different between people who have been shown pictures of spiders and people who have been shown a real spider at 5% significance level. The null and alternative hypothesis is, The t-test statistics is, From the SPSS output, thet-test statistics is -1.681] Thep-value for this test is, From the SPSS output, thep-value for this test is |0.107 Decision

The conclusion is that p-value in this context is higher than 0.05 which is 0.107, so the null hypothesis is not rejected at 5% level of significance. There is insufficient evidence to indicate that the mean of spider phobia level is different between people who have been shown pictures of spiders and people who have been shown a real spider. The result is not statistically significant
