5. Answer question 2

We would like to assess if, on average, there is a significant difference
in the amount time (in seconds) it takes to write a full name
(difference = writing hand - non-writing hand) for all fırst-grade
children in the US. The hypotheses are: Ho: Hd = 0 versus Ha: Hd # 0
and a 2% significance level is selected.
1. After conducting the appropriate test, the researcher rejects
Ho at a 2% significance level. Using the same data, which of the
following intervals would be a reasonable 98% confidence
interval for u? [ Select ]
2. The research prefers to use QQ plots over histograms for
checking normality assumptions in general. How many QQ plots
would the researcher need to make for this study?
v [ Select ]
1 QQ plot
3 QQ plots
robability of
3
2 QQ plots
[ Select j
concluding that Hd # 0.
