Use LaTeX: hat{p}=dfrac{137}{291}approx 0.47


p ^ = 137 291 0.47
to answer the following questions.

Is the theory-based approach valid for this study?

Use the theory-based applet to calculate the upper bound of the 90% CI. Round to 4 decimal places.

If a 99% CI for pi
π
is (0.3423,0.3874), what was the value of hat{p}
p ^
in this study? Round to 3 decimal places.
