random sample of ten professional athletes produced the following data. The first row is the number of endorsements the athlete has and the second row is the amount of money made (in millions of dollars) by the athlete. If a professional athlete did 2 endorsements, what is the residual for this data point? Round to one decimal point.

Please answer all questions with clear handwriting.
(1) A glass jar contains 2 red, 3 green, 2 blue, and 4 yellow marbles. If a single marble is chosen at random from the jar, what is the probability that it is yellow or green?
(2) After watching a theatric show, a group of 3 people go to the reception to get their hats back. If they get the hats back in random order. What is the chance that at least one gets the correct hat?
(3)What is the probability of this event for a group of 4 people?

A random sample of size n = 71 is taken from a population of size N = 639 with a population proportion p = 0.73.
a-1. Is it necessary to apply the finite population correction factor?
a-2. Calculate the expected value and the standard error of the sample proportion. (Round "expected value" to 2 decimal places and "standard error" to 4 decimal places.)
b. What is the probability that the sample proportion is less than 0.66? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)

A study of reading comprehension in children compared three methods of instruction. The three methods of instruction are called Basal, DRTA, and Strategies. As is common in such studies, several pretest variables were measured before any instruction was given. One purpose of the pretest was to see if the three groups of children were similar in their comprehension skills. The READINGdata set described in the Data Appendix gives two pretest measures that were used in this study. Use one-way ANOVA to analyze these data and write a summary of your results.

A study of reading comprehension in children compared three methods of instruction. The three methods of instruction are called Basal, DRTA, and Strategies. Basal is the traditional method of teaching, while DRTA and Strategies are two innovative methods based on similar theoretical considerations. The READING data set includes three response variables that the new methods were designed to improve. Analyze these variables using ANOVA methods. Be sure to include multiple comparisons or contrasts as needed. Write a report summarizing your findings.
