**Exhibit 13-31**To test whether or not there is a difference between treatments A, B, C, and D, a sample of 12 observations has been randomly assigned to the four treatments. You are given the results below.| Treatment | Observation ||-----------|-----------------|| A | 30, 25, 33 || B | 26, 20, 28 || C | 30, 28, 22 || D | 26, 34, 28 |Refer to Exhibit 13-31. The null hypothesis for this ANOVA problem is _____.- ☐ \( \mu_1 = \mu_2 \)- ☐ \( \mu_1 = \mu_2 = \mu_3 \)- ☐ \( \mu_1 = \mu_2 = \mu_3 = \mu_4 \)- ☐ \( \mu_1 = \mu_2 = \ldots = \mu_{12} \)**Explanation:**This exhibit represents data for an Analysis of Variance (ANOVA) test. Four treatments (A, B, C, D) have been applied, each with three observations. The goal of the ANOVA test is to determine if there are any statistically significant differences between the means of these treatments. The null hypothesis states that all treatment means are equal. Hence, the correct null hypothesis is represented by the option \( \mu_1 = \mu_2 = \mu_3 = \mu_4 \).

You have determined that in the past three years there 7 of the 14 were hand injuries. Previous projections had indicated that under normal conditions, only four hand injuries were expected and 12 other injuries were expected. The remaining injuries were due to other causes. Calculate the chi-square value and discuss whether there was a significant difference in observed data vs. the expected data. Also discuss how the process of hypothesis testing might prove helpful o = 7 hand injuries and 7 other injuriese = 4 expected hand injuries and 12 other injuries

On March 2005, a poll surveyed 535 adults aged 18 years old or older and asked “ Do you think there is life on other planets or not?. Of the 535, 326 responded yes. same question was asked on September3,2000, 385 of the 535 individuals surveyed said yes. Can you conclude that the proportion has decreased at alpha = 0.05 level of significance.

For the general population, the average fatigue level is μ = 50. A researcher is testing the hypothesis that engaging a meditation exercise reduces employee fatigue. A sample of n = 30 participants is obtained, and each participant engaged in a meditation exercise for 20 minutes at work each workday for a month. This sample’s average fatigue level was M = 46 with a sample variance of 100 after the month. Please write out the four steps for this hypothesis test assuming an alpha level of .05. Step 1: State your hypotheses Step 2: Find your critical regions in a distribution Step 3: Data Analysis Step 4: Making a decision
