**Step-by-Step Hypothesis Testing:****(b) Decision Rule for 0.05 Level of Significance:**- **Rule:** Reject the null hypothesis if the test statistic $ t_{calc} < -2.36 $ or $ t_{calc} > 2.36 $.**(c-1) Finding the Test Statistic $ t_{calc} $:**- **Calculated Value:** $ t_{calc} = -0.90 $**(c-2) Conclusion:**- **Decision:** We fail to reject the null hypothesis.**Explanation:**- The decision to reject or not reject the null hypothesis is based on the comparison of the calculated $ t $-value against the critical values (-2.36 and 2.36). Since $ t_{calc} = -0.90 $ does not fall outside the range (-2.36, 2.36), the null hypothesis is not rejected. A certain company will purchase the house of any employee who is transferred out of state and will handle all details of reselling the house. The purchase price is based on two assessments, one assessor being chosen by the employee and one by the company. Based on the sample of eight assessments shown, do the two assessors agree? Use the .05 level of significance.**Assessments of Eight Homes ($ thousands)**``` | Home 1 | Home 2 | Home 3 | Home 4 | Home 5 | Home 6 | Home 7 | Home 8-----------------------------------------------------------------------------------------Company | 325 | 345 | 455 | 279 | 292 | 281 | 539 | 747Employee | 312 | 350 | 480 | 287 | 304 | 284 | 521 | 770```[Excel Data File Link]### (a) Choose the appropriate hypotheses. Assume $ d = \text{company assessed value} - \text{employee assessed value} $.- $ H_0: \mu_d = 0 $ versus $ H_1: \mu_d \neq 0 $.- $ H_0: \mu_d \neq 0 $ versus $ H_1: \mu_d = 0 $.### (b) State the decision rule for .05 level of significance. (Round your answers to 2 decimal places. A negative value should be indicated by a minus sign.)Reject the null hypothesis if $ t_{calc} < -2.36 $ or $ t_{calc} > 2.36 $. ✔### (c-1) Find the test statistic $ t_{calc} $. (Round your answer to 2 decimal places. A negative value should be indicated by a minus sign.)

Cloud seeding, a process in which chemicals such as silver iodide and frozen carbon dioxide are introduced by aircraft into clouds to promote rainfall was widely used in many years. Recent research has questioned its effectiveness. An experiment as performed by randomly assigning 52 clouds to be seeded or not. The amount of rain generated was then measured in acre-feet. The box plot of the data for the seeded and unseeded clouds are shown in the figure. Which statement best interprets the box plot. Boxplot of Seeded, Unseeded 3000 f 2500어 2000 - 1500 - 1000 - 500- Seeded Unseeded a. Cloud seeding is somewhat effective in promoting rainfall because of the greater mean b. Outliers for both seeded and unseeded data may prove data on the effectiveness of cloud seeding is insufficient c. Extreme outliers are evident in the seeded data and has greater variance O d. There's a greater mean and greater dispersion in the seeded data. Both plots show outliers Data
