Question

If you can help me with 1-6 that would be great thank you!

Scenario 1: Sexes of birds In an ecological study of the Carolina Junco, 53 birds were captured from a certain population; of these, 40 were male. Is this evidence that males outnumber females in the broader population? The researchers used this sample data to conduct a test of the hypotheses below... H : p = 0.5 vs H ip > 0.5 ...where p is defined as the true proportion of the Carolina Junco population that is male. The resulting test statistic was 7 = 3.7087 with a p-value = 0.000104 and estimated effect size of h = 0.5345 Question 1 (1 point) Which of the following is the most appropriate conclusion that one could draw from the results of this hypothesis test? We have extremely strong evidence against the claim that p -0.5 and for the claim that p = 0.7547. The probability that the null hypothesis is true is only 0.000104, so we should choose to reject it. We have extremely strong evidence that the model assuming the ratio of male- to-females in the Carolina Junco population is 1:1 does not fit our observed data. None of these is an appropriate conclusion to this hypothesis test.

Don't ANSWER THESE THEY WERE POSTED BY MISTAKE!!!!!

Answer 1

ANSWER 1 :

Given that  

Ho : P = 0.5

Ha : P > 0.5

Z = 3.7087

p - value = 0.000104

The probability that the null hypothesis is there is only 0.000104, so we should choose to reject it.
