英语统计学题目 求助(T_T)
consumer products are required bylaw to contain at least as much as the amount printed on the package.For example a bag of potato chipsthat is labeled as 10 ounces should contain at least 10 ounces.Assume that the standard deviation of the packaging equipment yields a bag weight standard deviation of 0.2ounces.Explain what average bag weight must be used to achieve at least 97.5 percent of the bags having 10 or more ounces in the bag Assume the bag weight distribution is bell-shaped.

给你翻译成中文,重新开个题目问吧,手边没有概率分布表,然后你的题目没贴完整,假设检验问题,H0：u>=10,标准差s=0.2,求在置信水平为97.5%.可能是置信区间也可能是拒绝原假设的概率.
