Transcribed Image Text:The average child has 10 toys on their Christmas List. Is the mean different for Christmas Lists of children
in Walnut, California? The data show the results of a survey of 14 children in Walnut who were asked how
many toys they have in their Christmas List. Assume that the distribution of the population is normal.
9, 10, 9, 10, 9, 9, 7, 7, 8, 8, 11, 7, 11, 10
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 v
Hj: ?v
Select an answer v
c. The test statistic
(please round your answer to 3 decimal places.)
d. The p-value =
(Please round 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 populaton mean is significantly different from 10 at a = 0.10, so there is
sufficient evidence to conclude that the population mean number of toys on the Christmas List
of children in Walnut is different from 10.
O The data suggest that the population mean number of toys on the Christmas List of children in
Walnut is not significantly different from 10 at a = 0.10, so there is insufficient evidence to
conclude that the population mean number of toys on the Christmas List of children in Walnut
is different from 10.
O The data suggest the population mean is not significantly different from 10 at a = 0.10, so
