Decide and state whether a one-sample z test, a two- sample z test, or a t test is appropriate. Whichever test you choose, state your null hypothesis, then obtain a P -value and formulate a valid conclusion.

Answer #1

We have to test, is coin fair or not?

so here we have to use one sample proportion Z test.

If we consider alpha=0.05

P-value>alpha

Therefore, we fail to reject Ho.

That is, we can say that coin is fair.

You are interested in testing if a coin is fair. That is, you are conducting the hypothesis test: H0 : P(Heads) = 0.5 Ha : P(Heads) ≠ .5 If you flip the coin 1,000 times and obtain 560 heads. Calculate the P-value of this test, and decide whether or not to reject the null hypothesis at the 5% significance level.

If you flip a fair coin, the probability that the result is heads will be 0.50. A given coin is tested for fairness using a hypothesis test of H0:p=0.50H0:p=0.50 versus HA:p≠0.50HA:p≠0.50. The given coin is flipped 240 times, and comes up heads 143 times. Assume this can be treated as a Simple Random Sample. The test statistic for this sample is z= The P-value for this sample is If we change the significance level of a hypothesis test from 5%...
