Let's pretend that you had two samples, both of sample sizes 30, and between the two samples: one sample has 12 people like apple pie better, and the other has 18 people like pumpkin pie better. I would like to test this at a 0.05 significance level to see if more people eat more pumpkin pie than Apple pie.

    Question 17 (1 point) Let's say that i take our class to be a SRS and gather data on everyone's weight. Taking that sample we see that our sample mean is 68 kilograms. Assume that we magically know that the true population standard deviation is 10 kilograms. Based on our data, gathered from 40 students, can you give me an estimate on the true population mean weight? Give me a 95% Confidence interval O (64.9,71.1) (66.4, 69.92) (62, 74.2) (58.1,...

    1) Consider two independent random samples of sizes n1 = 14 and n2 = 14, taken from two normally distributed populations. The sample standard deviations are calculated to be s1= 1.98 and s2 = 5.71, and the sample means are x¯1=-10.2and x¯2=-2.34, respectively. Using this information, test the null hypothesis H0:μ1=μ2against the one-sided alternative HA:μ1<μ2, using Welch's 2-sample t Procedure for independent samples. a) Calculate the value for the t test statistic. Round your response to at least 2 decimal...
