According to the Carnegie unit system, the recommended number of hours students should study per unit is 2. Are statistics students' stucdy hours less than the recommended number of hours per unit? The data show the results of a survey of 15 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population. 3.1, 0, 0, 1.3, 1.3, 0.6, 0, 2.9, 1.1, 3.1, 2.1, 0.6, 1.1, 2.3, 0.1 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: 2 v Select an answer H: ? v Select an answer c. The test statistic ? (please show your answer to 3 decimal places.)

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Thank you
![According to the Carnegie unit system, the recommended number of hours students should study per unit
is 2. Are statistics students' study hours less than the recommended number of hours per unit? The data
show the results of a survey of 15 statistics students who were asked how many hours per unit they
studied. Assume a normal distribution for the population.
3.1, 0, 0, 1.3, 1.3, 0.6, 0, 2.9, 1.1, 3.1, 2.1, 0.6, 1.1, 2.3, 0.1
What can be condluded 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 v
H: ? vSelect an answer v
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.)
e. The p-value is ? v a
f. Based on this, we should Select an answer V the null hypothesis.
g. Thus, the final conclusion is that ..
O The data suggest the population mean is not significantly less than 2 at a = 0.10, so there is
sufficient evidence to conclude that the population mean study time per unit for statistics
students is equal to 2.
O The data suggest that the population mean study time per unit for statistics students is not
significantly less than 2 at a = 0.10, so there is insufficient evidence to conclude that the
population mean study time per unit for statistics students is less than 2.
O The data suggest the populaton mean is significantly less than 2 at a = 0.10, so there is
sufficient evidence to conclude that the population mean study time per unit for statistics
students is less than 2.
h. Interpret the p-value in the context of the study.
O There is a 1.69186863% chance that the population mean study time per unit for statistics
students is less than 2.
O There is a 1.69186863% chance of a Type I error.
