Question

Laura flipped a coin 64 times and obtained 28 heads. To determine if these results suggest that the coin is weighted against heads, she performed the following hypothesis test: $H_0: p \ge 0.5$ $H_a: p < 0.5$ $\alpha = 0.10$ Calculate the test statistic for this hypothesis test (round your answer to 2 decimal places) Provide your answer below: Test Statistic =

          Laura flipped a coin 64 times and obtained 28 heads.

To determine if these results suggest that the coin is weighted against heads, she performed the following hypothesis test:

$H_0: p \ge 0.5$
$H_a: p < 0.5$

$\alpha = 0.10$

Calculate the test statistic for this hypothesis test (round your answer to 2 decimal places)

Provide your answer below:

Test Statistic =

Step 1

Given information: - Number of trials (coin flips), $n = 64$ - Number of successes (heads obtained), $x = 28$ - Null hypothesis, $H_0: p \ge 0.5$ - Alternative hypothesis, $H_a: p < 0.5$ - Significance level, $\alpha = 0.10$ The formula for the test statistic Show more…
