**Exhibit 13-12**- **SSTR = 736**- **SSE = 900**- **nₜ = 18****Hypotheses:**- Null Hypothesis (H₀): μ₁ = μ₂ = μ₃- Alternative Hypothesis (Hₐ): At least one mean is different**Instruction:**Refer to Exhibit 13-12. The null hypothesis is to be tested at the 5% level of significance. The critical value from the table is _____.**Options:**- 2.87- 3.24- 3.68- 8.7**Explanation:**This problem involves testing whether the means of three groups are equal, using a significance level of 5%. The Sum of Squares for Treatment (SSTR) and Sum of Squares for Error (SSE) are provided, along with the total sample size (nₜ). The critical value must be selected from the given options using appropriate statistical tables based on the degrees of freedom associated with the ANOVA test.

Given that There are 3 treatments dfTreatments = 3 - 1 = 2 nT = 18 dfT = 18 - 1 = 17 dfError =…

The Department of Agriculture wants to determine whether the mean yield per acre for a particular variety of soybeans is different this year compared to the historical avg yield of 520 bushels per acre. Thus, the null and alternative hypotheses are Ho: mu = 520 Ha: mu is not = to 520 You set out to conduct a hypothesis test at the 95% level. Mean yields are distributed Normally. You take a sample of 36 different acres. From this sample, you calculate a mean yield of 573 and a std deviation of 124. What is the test statistic for this hypothesis test? (To two decimal places. ex: 1.23)
A normal population has a mean of μ = 25 on a communication effectiveness scale. After receiving a treatment, a sample of n = 4 scores yields the following data: 20, 28, 20, 20. Is there evidence for a significant treatment effect? Use an alpha level of .05.
Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of three comparison treatments. Each participant takes the assigned medication and his or her systolic blood pressure is recorded after 6 months on the assigned treatment. The data are shown in Table 7–58. Is there a difference in mean systolic blood pressure among treatments? Run the appropriate test at α = 0.05.
