Use the following information to answer Q30 - Q32
A study of 25 long distance phone calls from the office of a certain company reveals that the
mean length of time per call was 16.5 minutes with standard deviation 6.0 minutes. At a =
0.05 significance level, test the company's claim that the average time spent on long distance
calls from the office is less than 15.0 minutes.
In this case, the alternate hypothesis is
O Ha:

The work week for adults in the US that work full time is normally distributed with a mean of 47 hours. A newly hired engineer at a start-up company believes that employees at start-up companies work more on average then most working adults in the US. She asks 12 engineering friends at start-ups for the lengths in hours of their work week. Their responses are shown in the table below. Test the claim using a α=0.05 level of significance.

The mean number of eggs per person eaten in the United States is 266. Do college students eat a different number of eggs than the average American? The 61 college students surveyed averaged 285 eggs per person and their standard deviation was 72.6. What can be concluded at the a= 0.10 level of significance? a.

Using α=0.10 is there evidence to suggest the actual average length of stay for this surgical procedure is 3 days? The correct conclusion is that we Select an answer: (can, maybe can, cannot) conclude that the average length of stay of Select an answer: (all, sampled, randomly selected) surgeries of this type Select an answer: (is less than, is is different from, is more than) Select an answer: (3.23, 0.85, 3) days.What level of concern do you have for the validity of your results? Moderate - the original data is not normally distributed which is an assumptions violation Low - our sample size is near 30, so while that's likely sufficient for X¯ to be approximately normally distributed, seeing that the original data isn't extremely skewed would make us feel more comfortable Extreme - we…
