# Essays on Data Analysis Assignment

The paper "Data Analysis " is a perfect example of a business assignment. In this research study, several hypotheses were formulated based on the respective research questions. Appropriate tests were used to analyze and measure the differences in the tested variables. For all the statistical analyses, the alpha level of significance is set at. 05. Results Question 1: To test whether the average amount that the people are willing to pay for each meal is less than the forecasted value of \$ 19, formulate the null hypothesis (hypothesis 1) and test it against an alternative hypothesis. Hypothesis 1: The null hypothesis stated that the average amount that the people are willing to pay for each meal is equal to the forecasted value of \$ 19, while the alternative hypothesis stated that the average amount that the people are willing to pay for each meal is less than the forecasted value of \$ 19.

For the sample selected, the average amount that the people are willing to pay for each meal (M = \$19.23, SD = 7.56) is greater than the hypothesized value.

The result of one sample t-Test revealed a non-significant difference, t (399) = . 609, p = . 272, at the alpha level of significance. 05. Thus, fail to reject the null hypothesis. Therefore, the average amount that the people are willing to pay for each meal is not less than the forecasted value of \$ 19. Question 2: To test whether the average income of the people surveyed differs from the hypothesized value of \$70,000, formulate a null hypothesis (hypothesis 2) and test it against an alternative hypothesis. Hypothesis 2: The null hypothesis stated that the average income of the people that were surveyed is equal to \$70,000, while the alternative hypothesis stated that the average income of the people that were surveyed differs significantly from \$70,000.

The sample survey average income (M = \$77,087.50, SD = 28,896.93) is greater than the hypothesized value. The result of one sample t-Test revealed a significant difference, t (399) = 4.905, p < .001.
