A communication network transmits binary digits, 0 to 1, where each digit is transmitted 10 times in succession. During each transmission, there is a 0.995 probability of accurate transmission.
1) Construct the transition matrix.
2) What is the probability of a digit entering the network will be recorded accurately after the last transmission? Assume the probability of an accurate transmission per digit has improved to 0.998, 3).
Find the new probability for question 2.
Compare your best difference to the result from an ordinary two-sample t-test between these groups. Comment the difference.
Do the data provide significant support for any preferences among the three brands? Test At the .05 level of significance.
Use confidence interval to determine the estimated margin of error, Then determine the sample mean.
Find out the p-value associated with test of hypothesis you conducted?
Assume that the significance level is a= 0.1. Use the given information to find the p-value and the critical value (s). With H1: p = with line through it 1/2 the test statistic is z= - 1.35
If not what would be a better testing strategy? Could you form a Null Hypothesis or an Alternative Hypothesis? If yes, what would they be.
