Since testing Ha: p >.80, p-value is the area in the upper tail, or to the right of z-value. Looking at the Table, find percentile associated with z=1.97 = 2.0 ( 97.73%, but that’s area to the left, since we need area to the right we do: 1- .9773 = 0.0227. p-value = 0.0227. By default we compare p-value with 0.05 significance level and see ...

The coin is tossed 50,000 times, and 25,250 heads result. Using a significance level of 0.05, would you reject the assertion that the coin is fair? Specify the hypothesis. Show test statistics=2.24. Either compute the P-value (=0.025) or by looking at the rejection region, make a decision (Fail to reject H0/Reject H0) Write the conclusion

How to find P-value. Find the P-value for a left-tailed test with a test statistic of z = -2.23. Decide whether to reject H0 if the level of significance is α = 0.01. From the normal table z = -2.23 is P= 0.0129 which is the area in the left tail. Since 0.0129 > 0.01, you should fail to reject H0.
