Question

(Choose 1 answer) A study involves 634 randomly selected deaths. with 32 of them caused by accidents. Construct a \( 98 \% \) confidence interval for the true percentage of all deaths that are caused by accidents. \[ \begin{array}{l} \text { A. } 3.34 \%<n< \\ 6.75 \% \\ \text { B. } 3.61 \%<n< \\ 6.48 \% \\ \text { C. } 2.80 \%<n< \\ 7.29 \% \end{array} \] D. None of the other choices is correct E. \( 3.02 \%<n< \) 7.07\% Let \( z_{0.01}=2.33 \)

A study involves 634 randomly selected deaths. with 32 of them caused by accidents. Construct a 98 % confidence interval for the true percentage of all deaths that are caused by accidents.

A. 3.34 %<n<

6.75 %
B. 3.61 %<n<

6.48 %
C. 2.80 %<n<

7.29 %

D. None of the other choices is correct
E. 3.02 %<n< 7.07%
Let z0.01=2.33

Step 1

- Number of deaths (\( n \)) = 634 - Number of deaths caused by accidents (\( x \)) = 32 - Confidence level = 98% - \( z \)-value for 98% confidence level (\( z_{0.01} \)) = 2.33 Show more…
