Women are recommended to consume 1750 calories per day. You suspect that the average calorie intake is larger for women at your college. The data for the 13 women who participated in the study is shown below: 1592, 1965, 1720, 2040, 1929, 1844, 1747, 1776, 1666, 1619, 2027, 1718, 1626 Assuming that the distribution is normal, what can be concluded at the αα = 0.05 level of significance? For this study, we should use Select an answer z-test for a population proportion t-test for a population mean The null and alternative hypotheses would be: H0:H0: ? p μ Select an answer ≠ = > < H1:H1: ? μ p Select an answer > < = ≠ The test statistic ? t z = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? > ≤ αα Based on this, we should Select an answer fail to reject reject accept the null hypothesis. Thus, the final conclusion is that ... The data suggest the population mean is not significantly more than 1750 at αα = 0.05, so there is sufficient evidence to conclude that the population mean calorie intake for women at your college is equal to 1750. The data suggest that the population mean calorie intake for women at your college is not significantly more than 1750 at αα = 0.05, so there is insufficient evidence to conclude that the population mean calorie intake for women at your college is more than 1750. The data suggest the populaton mean is significantly more than 1750 at αα = 0.05, so there is sufficient evidence to conclude that the population mean calorie intake for women at your college is more than 1750. Interpret the p-value in the context of the study. If the population mean calorie intake for women at your college is 1750 and if you survey another 13 women at your college then there would be a 18.80892972% chance that the population mean calorie intake for women at your college would be greater than 1750. There is a 18.80892972% chance that the population mean calorie intake for women at your college is greater than 1750. If the population mean calorie intake for women at your college is 1750 and if you survey another 13 women at your college then there would be a 18.80892972% chance that the sample mean for these 13 women would be greater than 1790. There is a 18.80892972% chance of a Type I error. Interpret the level of significance in the context of the study. There is a 5% chance that the population mean calorie intake for women at your college is more than 1750. If the population mean calorie intake for women at your college is 1750 and if you survey another 13 women at your college, then there would be a 5% chance that we would end up falsely concuding that the population mean calorie intake for women at your college is more than 1750. There is a 5% chance that the women at your college are just eating too many desserts and will all gain the freshmen 15.

Assuming that the distribution is normal, what can be concluded at the αα = 0.05 level of significance?

For this study, we should use Select an answer z-test for a population proportion t-test for a population mean
The null and alternative hypotheses would be:

H0:H0: ? p μ Select an answer ≠ = > <

H1:H1: ? μ p Select an answer > < = ≠

The test statistic ? t z = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is ? > ≤ αα
Based on this, we should Select an answer fail to reject reject accept the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population mean is not significantly more than 1750 at αα = 0.05, so there is sufficient evidence to conclude that the population mean calorie intake for women at your college is equal to 1750.
- The data suggest that the population mean calorie intake for women at your college is not significantly more than 1750 at αα = 0.05, so there is insufficient evidence to conclude that the population mean calorie intake for women at your college is more than 1750.
- The data suggest the populaton mean is significantly more than 1750 at αα = 0.05, so there is sufficient evidence to conclude that the population mean calorie intake for women at your college is more than 1750.
Interpret the p-value in the context of the study.
- If the population mean calorie intake for women at your college is 1750 and if you survey another 13 women at your college then there would be a 18.80892972% chance that the population mean calorie intake for women at your college would be greater than 1750.
- There is a 18.80892972% chance that the population mean calorie intake for women at your college is greater than 1750.
- If the population mean calorie intake for women at your college is 1750 and if you survey another 13 women at your college then there would be a 18.80892972% chance that the sample mean for these 13 women would be greater than 1790.

Interpret the level of significance in the context of the study.
