How can i answer all parts to this question pls?
An experiment on beans was performed to investigate the environmental effects of salinity and water temperature on sprouting. Forty beans were randomly allocated to each of 36 petri dishes that were subject to one of four levels of salinity (0, 4. 8. and 12 ppm) and one of three temperatures (32, 34, or 36C). The students kept track of the number of beans sprouting (out of 40) for each of the 36 dishes. Complete parts a and b. a Click here to view the ANOVA table. a) State the hypotheses about the factors. Lety represent the effect of the Salinity level. Choose the correct hypotheses below. 0 A. Ho: 11 = 12 = 13 O 3. Ho: Not all cfthe Salinity levels have the same effect on Sprouts. HA: Not all of the Salinity levels have the same effect on Sprouts. HA1 \"I1 =72 =73 =74 O c. Ho: Y1 = y2 = '13 = 14 O D. Ho: Not all of the Salinity levels have the same effect on Sprouts. HA: Not all of the Salinity levels have the same effect on Sprouts. HA: 11 =12 =73 Let'r represent the eect of the Temperature level. Choose the correct hypotheses below. 0 A. Ho: 11 = 1:2 = 1:3 =14 O B. H0: Not all of the Temperature levels have the same effect on Sprouts. HA: Not all of the Temperature levels have the same effect on Sprouts. HA: :1 =12 =13 = 14 O c. Ho: 1:1 = 1:2 = 1:3 0 D. Ho: Not all of the Temperature levels have the same effect on Sprouts. HA: Not all of the Temperature levels have the same effect on Sprous. H A: 11 =12 =13 State the hypotheses about the interaction. Choose the correct answer below. 0 A. H0: All of the interaction terms are 0. O B. H0: The interaction terms are all 0. HA: All of the interaction terms are not 0. HA: There is an interaction effect. 0 0. Ho: All ofthe interaction terms are not 0. O D. Ho: There is an interaction effect. HA: All of the interaction terms are 0. H A: The interaction terms are all 0. b) Perform the hypothesis tests and state your conclusion. Assume partial boxplots show that the variances are roughly equal. An interaction plot shows that the plots for Salinity and Temperature are roughly parallel. The conditions for the two-way ANOVA are met. Use a = 0.05. Identify the test statistic for the interaction term Salinity x Temp. (Type an integer or a decimal.) Identify the P-value for the interaction term Salinity x Temp. Type 0 if the P-value is less than 0.0001. (Type an integer or a decimal.) What would you conclude about the interaction term Salinity x Temp? O A. Reject Ho. There is no significant interaction between Salinity and Temperature. O B. Fail to reject Ho. There is no significant interaction between Salinity and Temperature. O C. Reject Ho. There is significant interaction between Salinity and Temperature. O D. Fail to reject Ho. There is significant interaction between Salinity and Temperature. Identify the test statistic for the factor of Salinity. (Type an integer or a decimal.) Identify the P-value for the factor of Salinity. Type 0 if the P-value is less than 0.0001. (Type an integer or a decimal.) What would you conclude about the factor of Salinity? O A. Reject the null hypothesis. There is no evidence that the number of Sprouts is not equal across all Salinity levels. O B. Reject the null hypothesis. There is evidence that the number of Sprouts is not equal across all Salinity levels. O C. Fail to reject the null hypothesis. There is no evidence that the number of Sprouts is not equal across all Salinity levels.Identify the test statistic for the factor of Temperature. E (Type an integer or a decimal.) Identify the P-value for the factor of Temperature. Type 0 if the P-value is less than 0.0001. E (Type an integer or a decimal.) What would you conclude about the factor of Temperature? 0 A. Reject the null hypothesis. There is no evidence that the number of Sprouts is not equal across all Temperature levels. 0 B. Fail to reject the null hypothesis. There is no evidence that the number of Sprouts is not equal across all Temperature levels. 0 C. Reject the null hypothesis. There is evidence that the number of Sprouts is not equal across all Temperature levels. Sum of Mean Source DF F-ratioP-value Squares Square Salinity 32000.905 667.0 52.686Step by Step Solution
