Statistics question: a sample of 25 families was taken for a study. the objective of the study was to estimate the factors that determine the monthly expenditure (in dollars) on food for families. the independent variables included in the analysis were the number of members in the family (x1), the number of meals eaten outside (x2), and a dummy variable (x3) that equals 1 if a family member is on a diet and equals 0 if there is no family member on a diet. the following regression results were obtained.                                       coefficients             standard error intercept                        450.08                       53.6 x1                                  49.92                         9.6 x2                                  10.12                         2.2 x3                                  -.60                           12.0   ANOVA                                         df                          SS                      MS regression…

To test for any significant difference in the number of hours between breakdowns for four machines, the following data were obtained. Machine Machine Machine Machine 1 2. 3 4 6.7 9.0 10.9 9.8 8.1 7.5 10.2 12.5 5.6 9.7 9.4 11.8 7.7 10.3 10.1 10.6 8.6 9.4 9.1 11.2 7.7 9.9 8.5 11.3 (a) At the a = 0.05 level of significance, what is the difference, if any, in the population mean times among the four machines? State the null and alternative hypotheses. O Ho: H1 = H2 = H3 = H4 H: Not all the population means are equal. O Ho: At least two of the population means are equal. H.: At least two of the population means are different. O Ho: H1 = H2 = H3 = H4 O Ho: Not all the population means are equal. H: H, = H2 = Hz=H4 O Ho: H1 + H2 # Hz# H4 H: Hq = Hq = Hz =H4 Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) p-value = State your conclusion. O Do not reject H.. There is not sufficient evidence to…
