■. Lydia is trying to answer the question: "How much do large eggs weigh?" She collects 15 large eggs and measures the following weights in grams: 55,51,58,59, 59,59,60,6 9 10 11 12 13 14 15 562 58, 62, 57, 60, 62, 65, 59, 61, 55, 60, 63, 59, 81, 62, 59 62,62,63,65 81 (a) Explain why Lydia's question requires statistics to answer. [2 points] Lydia's question requires statistics to answer because not all large eggs weigh the same so we nued an averag of how much they weich (b) Find the mean and standard deviation for this sample. Round both measures to the nearest tenth. [2 points] The mean is 61.5 and the stand ard deviation for the sample is 5 (c) How many of the 15 data values fall within one standard deviation of the mean? Show how your answer.

This problem is fill in the blank. Just choose the correct answers. Thank you for your help A scientist has read that the mean birth weight, μ, of babies born at full term is 7.2 pounds. The scientist, believing that μ is less than this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 6.9 pounds and the standard deviation to be 1.7 pounds. Based on this information, answer the questions below. What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test? H0: (choose one) less than, less than or equal to, greater than, greater than or equal to, equal to, or not equal to. (choose one) 6.9 pounds, 7.2 pounds, or 1.7 pounds. H1: (Choose one) less than, less than or equal to, greater than, greater than or equal to, equal to, or not equal to. (Choose one) 6.9 pounds, 7.2 pounds, or 1.7 pounds. In the context…
