d) The confidence interval does not contain 24% ; I conclude FTR Ho. 30) See problems #21 & 22. State the non-technical conclusion. a) There is sufficient evidence to warrant rejection of the claim of Mars Inc. that 24% of their M & M's are blue. b) There is not sufficient evidence to warrant rejection of the claim of Mars Inc. that 24% of their M & M's are blue. c) The sample data support the claim of Mars Inc. that 24% of their M & M's are blue. d) There is not sufficient sample evidence to support the claim of Mars Inc. that 24% of their M & M's are blue. 31) Use your results of the last 10 problems. Did you prove that 24% of M & M candies are blue, as Mars Inc. claims? Explain. Bear in mind that a 'yes' or 'no' or other one-word answer is always wrong while a well-written statement with proper grammar and spelling exhibiting evidence of serious thought may well be counted correct, even if the conclusion is wrong.
21) Mars Inc., the company that produces M & M candies, claims that 24% of M & M candies are blue. A sample the author of your textbook conducted (see Data Set 13 in the 10th edition of this text) showed 13 Red, 8 Brown, 25 Orange, 8 Yellow, 27 Blue, and 19 Green M & M's. How many total M & M's were in this sample? 13T8+25+8+27+19 a) 98 b) 100 Ho:p> 24% Ha: p < 24% Original claim has equality a) 22) See problem #21. Use a 0.05 significance level to test the claim of Mars Inc. that 24% of their M & M's are blue. State the null and alternative hypotheses. c) 27 Ho:p ≤ 24% b) Ha:p> 24% d) 83 Ho:p= 24% Ho:p # 24% Ha: p+24%) Ha: p= 24%
