Based on the hypothesis, there is a clear need for larger sample sizes and additional testing because the confidence intervals for both the individual means are wide. There's a - 1.40 in the difference mean and it includes zero.. It also presented the confidence intervals for the mean driving distances and their difference. The new golf ball had a range of 264.3 to 270.6 yards. The confidence interval for the difference in means, from - 1.45 to 7.00 yards, suggests that the actual difference could be minimal or slightly favor either ball. That can mean that this overlap reinforces the conclusion that the new design does not provide a significant improvement in driving distance. This means that the new golf balls are better, maybe worse or like the current ones There's a similar size of 40 for each group, and they might be lacking insufficient power to detect small differences between the two golf ball models. I would increase the sample size so that way you'd identify significant differences better. Re-word this in a long substantive manner of 3 paragraphs. int Deviat 2.5 7.5 2.5 7.5 2.5 7.5 of Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 30 . Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 30 . The value of the mean is peas. (Type an integer or a decimal. Do not round.) The value of the standard deviation is peas. (Round to one decimal place as needed.) b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high. Values of 17.7 peas or fewer are significantly low. (Round to one decimal place as needed.) Values of peas or greater are significantly high. (Round to one decimal place as needed.)
