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. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: v Select an answer Hạ: Select an answer c. The test statistic ? v = (please show your answer to 3 decimal places.) d. The p-value= (Please show your answer to 4 decimal places.)

Question
Transcribed Image Text: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. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Но:
v Select an answer
H.:
vSelect an answer
c. The test statistic ?
(please show your answer to 3 decimal places.)
d. The p-value =
e. The p-value is ?
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that ...
(Please show your answer to 4 decimal places.)
a
O The data suggest that the sample mean is not significantly different from 266 at a = 0.10,
so there is statistically insignificant evidence to conclude that the sample mean number of
eggs consumed by college students per year is different from 285.
O The data suggest that the populaton mean is significantly different from 266 at a = 0.10, so
there is statistically significant evidence to conclude that the population mean number of
eggs consumed by college students per year is different from 266.
O The data suggest that the population mean is not significantly different from 266 at a =
0.10, so there is statistically insignificant evidence to conclude that the population mean
number of eggs consumed by college students per year is different from 266.
h. Interpret the p-value in the context of the study.
O There is a 4.53% chance of a Type l error.
O lf the population mean number of eggs consumed by college students per year is 266 and if
another 61 college students are surveyed then there would be a 4.53% chance that the sample
mean for these 61 students surveyed would either be less than 247 or greater than 285.
O There is a 4.53% chance that the population mean number of eggs consumed by college
students per year is not equal to 266.
O If the population mean number of eggs consumed by college students per year is 266 and if
another 61 college students are surveyed then there would be a 4.53% chance that the
population mean would either be less than 247 or greater than 285.
i. Interpret the level of significance in the context of the study.
O If the population mean number of eggs consumed by college students per year is 266 and if
another 61 college students are surveyed then there would be a 10% chance that we would
end up falsely concuding that the population mean number of eggs consumed by college
students per year is different from 266.
O If the population population mean number of eggs consumed by college students per year is
different from 266 and if another 61 college students are surveyed then there would be a
10% chance that we would end up falsely concuding that the population mean number of eggs
consumed by college students per year is equal to 266.
O There is a 10% chance that you will find the chicken that lays the golden eggs.
O There is a 10% chance that the population mean number of eggs consumed by college students
per year is different from 266.
