Now assume it is true that 60.98% of all words in the English language contain the letter "e" (as given in the source above). Generate a simulated distribution of 1000 sample statistics for simulated samples of 20 words from the English language. In the space below, include a copy-and-paste of your simulated distribution. You need to be using the "Proportion of Successes" option, and that is the picture you need to copy and paste. Your picture needs to show all the values that you entered in the applet. (h) If we used this simulated distribution of sample statistics and the 2SD rule to find the "cutoffs" for "usual" vs." unusual" sample statistics, then what would those cutoff values be? Find the values, and show all your work. (i) Which of the following conclusions does your observed sample statistic support? It is plausible that 60.98% of words in the English language contain the letter "e"? OR We have statistically significant evidence that the percentage of words in…
A manufacturer of colored candies states that 13% of the candies in a bag should be brown, 14% yellow, 13% red, 24% blue, 20% orange, and 16% green. A student randomly selected a bag of colored candies. He counted the number of candies of each color and obtained the results shown in the table. Test whether the bag of colored candies follows the distribution stated above at the a = 0.05 level of significance. Click the icon to view the table. = 22.323 (Round to three decimal places as needed.) What is the P-value of the test? P-value = 0.000 (Round to three decimal places as needed.) Based on the results, do the colors follow the same distribution as stated in the problem? A. Do not reject Ho. There is sufficient evidence that the distribution of colors is not the same as stated by the manufacturer. В. Do not reject Ho.
