Candace also knows that the class mean was 82 and standard deviation of 9. Because Candace loves this stuff and just can't get enough, she decides to determine the probability of obtaining a score at least as high as hers. Assuming the class scores are normallyr distributed. her probability is: O .3665 o .8665 .1335 O 1.111 0 none of the above If Candace also wants to know if her 4-person study group's mean of 89 was statistically significantly larger than the 40-person class mean of 82 (assume that the SD of her study group was 7), and she was willing to risk a Type I error in her decision 5 times out of 100, then which of the following would be her conclusion? O Her group did better than the class average and results were statistically significant. O Her group did better than the class average and results were not statistically significant. O Her group did not do better than the class average and results were statistically significant. O Her group did not do better than the class average and results were not statistically significant.
