larger or smaller P value. Juan and Mary want to test the null hypothesis that the mean length of text messages sent by students at their school is 10 character versus the alternative that it is less. Juan samples 100 text messages and finds the mean lengths to be 8.4 characters. Mary samples 100 messages and find the mean length to be 7.3 characters. Both Juan and Mary obtained the same standard deviation. will Juan P value be greater than, less than, or the same as Mary's P value ? explain

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. The health of employees is monitored by periodically weighing them in. A sample of 54 employees has a mean weight of 183.9 lb. Assuming that ? is known to be 121.2 lb, use a 0.10 significance level to test the claim that the population mean of all such employees weights is less than 200 lb.

1). Conduct the appropriate hypothesis test with the following information, and provide your p-value as your final answer.  The null hypothesis states that H0:= 250 versus the alternative Ha: > 250. The sample of size 26 resulted in a mean of 255.0 and a standard deviation of 8.79. Find the p-value in this example. 2). Conduct the appropriate hypothesis test with the following information, and provide your p-value as your final answer.  The null hypothesis states that H0: = 0.75 versus the...

Suppose that you want to test the null hypothesis that one-third of all adults in your county have a tattoo, against a two-sided alternative. In other words, you'd like to assess the hypotheses: (Ho: p = 0.33333) (Ha: p does not equal 0.33333) For each of the following parts, create your own example of a sample of 100 people that satisfies the indicated property. Do this by providing the sample numbers with a tattoo and without a tattoo. Also report...
