You would like to determine if the population probability of success differs from 0.70. You find 81 successes in 101 binomial trials. Implement the test at the 1% level of significance. Specify the null and the alternative hypotheses. Calculate the sample proportion. Note: Round your answer to 3 decimal places. Calculate the value of test statistic. Note: Round final answer to 2 decimal places.

You have data on the proportion of successes from two simple random samples: Group 1 Group 2 Sample Proportion 0.8 0.7 Sample Size 50 50 You wish to test whether the Group 1 population proportion is 0.13 higher than the Group 2 population proportion. Calculate the test statistic that you would use to perform this test. If necessary, round your answer to four decimal places.

In order to conduct a hypothesis test for the population proportion, you sample 300 observations that result in 111 successes. (You may find it useful to reference the appropriate table: table or table) Ho : p = 0.41; Ha: p ≠ 0.41 a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places ) Test statistic a-2. Find the p-value. 0.01 ≤ p-value < 0.025 0.025 ≤ p-value < 0.05 0.05 ≤ p-value < 0.10 p-value ≥ 0.10 p-value < 0.01
Use the normal approximation to find the indicated probability. The sample size is n, the population proportion of successes is p, and X is the number of successes in the sample n = 80, p=0.33; P(19<= X<=29)
