A researcher wishes to determine whether the foot size of Kryptonians is, on average, lower than the footsize of Daxamites. Independent simple random samples of 120 Kryptonians and 145 Daxamites yielded the following sample statistics for footSize: Use a significance level of 0.01 to test the claim that the mean footsize(cm) for Kryptoniants is lower than for the Daxamites. We are not sure if the variances are the same. The data is listed below. Complete the following analysis. 1. This is a [ Select ] right two left -tailed test. 2. The test statistic is equal to t=-0.70847 . 3. The P-value is equal to 0.2396 . 4. [ Select ] Reject Fail to reject the null hypothesis. 5. At the 1% significance level, the data [ Select ] indicates does not indicate that the mean footsize for Kryptonians is less than for Daxamites.

数据SA 外部网站链接。 网站有一份关于2011年至2015年10月某一天上午7点至晚上7点进出阿德莱德市自行车数量的统计数据集。 以下是数据集的摘录，包含了沿弗罗姆路（公路）以及穿越公园绿地的越野自行车道离开城市的自行车数量。我们认为多年来使用公路和越野的骑行者平均数量存在显著差异。 onroad <- c(219, 202, 226, 230) offroad <- c(239, 272, 265, 305) 检查是否有假设。用哪种代码来检验我们问题的假设最合适？
The DataSA Links to an external site. website has a dataset on the count of number of bikes entering and exiting the City of Adelaide from 7am-7pm on one day in October from 2011-2015. The following is an extract of the dataset which contains the number of bikes leaving the city on Frome Road (on-road), and via the off-road cycle path through the parklands. We think there's a significant difference in the mean number of cyclists using the on-road or off-road option over the years. onroad <- c(219, 202, 226, 230) offroad <- c(239, 272, 265, 305) Check for assumptions. Which is the most appropriate code to use to test our hypothesis for our question?
Determine if a paired t-test or independent two-sample t-test is appropriate: The basal average metabolic rate of seven chimpanzees is compared with the basal average metabolic rate of seven gorillas.
An experiment was conducted to evaluate the effectiveness of a treatment for a tapeworm in the intestines of dogs. IE Does treatment reduce the number of tapeworms? A random sample of worm-infected dogs of approximately the same ages and health status were randomly divided into two groups. Twelve of the dogs were injected with the drug and the remaining twelve were left untreated. After a six month period the number of worms in the intestines were counted. While not normal, the distributions of both the treated and untreated groups have similar shapes and no outliers. Output for both the pooled and not-pooled tests and basic statistics and graphs are below. What are the hypotheses for this test?
