A researcher wants to know if people from different social classes (lower, working, middle, upper classes) vary in their support for same-sex marriage.  The researcher measured the attitudes of people from different social classes toward same-sex marriage by asking if they think homosexuals should have right to marry (1=strongly disagree, 2=disagree, 3=agree, 4=strongly agree).  The researcher hypothesized that social classes will vary significantly in their support for same-sex marriage.  To test the hypothesis, the researcher conducted a one-way ANOVA and obtained the following results.   ANOVA HOMOSEXUALS SHOULD HAVE RIGHT TO MARRY    Sum of Squares df Mean Square F Sig. Between Groups 3.544 3 1.181 .496 .685 Within Groups 2202.349 924 2.383     Total 2205.892 927         Based on the results in the table above, can the researcher conclude that his hypothesis is supported and that there is a significant difference across different social classes in their support for same-sex marriage? Why or why not? Justify your reasoning.

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
