Women are recommended to consume 1900 calories per day. You suspect that the average calorie intake is
larger for women at your college. The data for the 15 women who participated in the study is shown below:
1971, 2079, 1941, 2169, 1807, 1989, 1981, 1758, 2012, 1966, 1915, 1926, 1942, 1961, 1800
Assuming that the distribution is normal, what can be concluded at the a = 0.05 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Họ: ? 8
Select an answer a
H1:
Select an answer
c. The test statistic ? e =
(please show your answer to 3 decimal places.)
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is ? 8 a
f. Based on this, we should Select an answer e the null hypothesis.
g. Thus, the final conclusion is that ..
The data suggest the population mean is not significantly more than 1900 ata = 0.05, so there is
sufficient evidence to conclude that the population mean calorie intake for women at your
college is equal to 1900.
O The data suggest the populaton mean is significantly more than 1900 at a = 0.05, so there is
sufficient evidence to conclude that the population mean calorie intake for women at your
college is more than 1900.
The data suggest that the population mean calorie intake for women at your college is not
significantly more than 1900 at a = 0.05, so there is insufficient evidence to conclude that the
population mean calorie intake for women at your college is more than 1900.
h. Interpret the p-value in the context of the study.
There is a 4.93846583% chance of a Type I error.
There is a 4.93846583% chance that the population mean calorie intake for women at your
college is greater than 1900.
Of the population mean calorie intake for women at your college is 1900 and if you survey another
15 women at your college then there would be a 4.93846583X chance that the sample mean for
these 15 women would be greater than 1948.
OIf the population mean calorie intake for women at your college is 1900 and if you survey another
15 women at your college then there would be a 4.93846583 chance that the population mean
calorie intake for women at your college would be greater than 1900.
1. 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
