The probability of error in the transmission of a binary digit over a communication [2] channel is 1=103. Write an expression for the exact probability of more than 3 errors when transmitting a block of 103 bits. What is its approximate value? Ass..
If they wish to estimate the population proportion within 0.03 and use 95 percent confidence, what is the largest random sample that they will need?
This company buys in equal volume from both suppliers, with half of the orders going to each supplier. What is the probability that a component to be installed is defective?
A random variable is normally distributed with a mean of 25 and a standard deviation of 5. If an observation is randomly selected from the distribution:
The amount in each can and find the average, the probability that the average of the six cans will be between 11.9 and 12.1 oz equals which standard normal probability?
Test hypothesis that mean weight of 2 sheets are equal against alternative that they are not(suppose equal variances). Use α=0.05 and suppose equal variances. Determine the P value.
A sample of 81 observations is taken from a normal population. The sample mean is 40, and the sample standard deviation is 5. Determine the 95 percent confidence interval for the population mean.
At the 5% significance level, can the researcher reject the hypothesis that the mean reading scores of all children in the three school systems is the same ? Formulate and test the appropriate hypotheses. Use the critical value approach.
Calculate the 95% confidence interval for the rate of positive tuberculin reaction separately for each of the two subpopulation, those with high exposure and those with low exposure.
