Suppose you are a manager for a local clothing store. You want to introduce a new product for an upcoming holiday. You design 6 new products, and take a sample of 21 customers per product design, to determine if any of the products provide a different value to consumers through a rating system. Your one-way ANOVA test reveals a SSTotal of 16976, along with a sum of squares between treatments (SST) of 1321. Using this information, conduct the appropriate one- way ANOVA test, with a significance level of 10%, to determine if any of the products provide a significantly different value to consumers (significantly different average rating). Select the correct results of your analysis, and if necessary, round your answer to two decimal places. Select all choices that apply

Is the proportion of wildfires caused by humans in the south higher than the proportion of wildfires caused by humans in the west? 356 of the 579 randomly selected wildfires looked at in the south were caused by humans while 322 of the 597 randomly selected wildfires looked at the west were caused by humans. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use z-test for the difference between two population proportions b. The null and alternative hypotheses would be: Ho: p1 p2 v (please enter a decimal) H1: p1 V p2 v (Please enter a decimal) c. The test statistic z v = 2.620 (please show your answer to 3 decimal places.) d. The p-value = 0.0213 e. The p-value is >v a f. Based on this, we should reject g. Thus, the final conclusion is that ... (Please show your answer to 4 decimal places.) |the null hypothesis. O The results are statistically significant at a = 0.01, so there is sufficient evidence to conclude that the proportion of the 579…

Suppose you are a manager for a local clothing store. You want to introduce a new product for an upcoming holiday. You design 8 new products, and take a sample of 16 customers per product design, to determine if any of the products provide a different value to consumers through a rating system. Your one-way ANOVA test reveals a SSTotal of 8762, along with a sum of squares between treatments (SST) of 1204. Using this information, conduct the appropriate one-way ANOVA test, with a significance level of 1%, to determine if any of the products provide a significantly different value to consumers (significantly different average rating). What is the correct result of your analysis? We cannot say that there is a significant difference in value to consumers between the products on average, since the F-statistic of the analysis is smaller than the critical value. We cannot say that there is a significant difference in value to consumers between the products on average, since the F-statistic of…

A sociologist is studying the age of the population in Blue Valley. Ten years ago, the population was such that 20% were under 20 years old, 14% were in the 20- to 35-year-old bracket, 30% were between 36 and 50, 24% were between 51 and 65, and 12% were over 65. A study done this year used a random sample of 210 residents. This sample is given below. At the 0.01 level of significance, has the age distribution of the population of Blue Valley changed? Under 20 20 - 35 36 - 50 51 - 65 Over 65 29 26 65 66 24 Please answer using excel A)  Find the sample test statistic. (Round your answer to two decimal places.) B) Find or estimate the P-value of the sample test statistic. C) Reject or Fail to Reject the Null Hypothesis
