Sample statistics for annual earning: High school diploma Bachelor's degree or higher X1= $27,136 X2= $34,329 %3D S1 = $2318 S2 = $4962 %3D n1 = 15 %3D n2 = 12 %3D The annual earnings of 15 people with a high school diploma and 12 people with a bachelor's degree or higher are shown above. Can you conclude that there is a difference in the mean annual earnings based on level of education? Use a = 0.01. Assume the populations are normally distributed and the population variances are not equal. a. Identify the claim and state Ho and Ha b. Identify the level of significance a and the degrees of freedom. c. Find the critical values and identify the rejection regions. d. Find the standardized test statistic t. Sketch a graph. e. Decide whether to reject the null hypothesis. f. Interpret the decision in the context of the original claim.

Describe all points that are 3 units away from the x-axis. What geometric structure do these points create?

(SUB-PART C ONLY PLEASE) Each row represents an experimental “run” (in this case, averaged sample of mango wine). Column A shows the run number; Column B shows the percentage of ethanol; Column C shows the amount of glycerol (in g/L); Column D shows the amount of acid (in g/L); Column E shows the temperature of the run (in °C); and Column F shows the pH of the run. Y represents Ethanol of mango wine. 1. Create a scatterplot of the ethanol data for all 20 runs (CREATED) a. Draw a graphical representation of the model that you chose to use. (CREATED WITHIN SCATTERPLOT) b. Comparing the model to your data, evaluate its fit in one or two sentences. (LINEAR MODEL; The conditions to say that the model is a good fit are as given below: To say that the model is the good fit, the coefficient of determination should be high. Atleast one the predictor variables should be statistically significant in predicting the response variable. ) c. Replace the generic Yi = β0 + ε with the information you…
