Assume that a random sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given statistics and confindence level.
98% confidence; the sample size is 2356, of which 25% are successes
The margin of error E = ___. (Round to four decimal places as needed.)

Describe appropriate treatment means μ1, μ2 and μ3. After that Test for statistically significant differences between these treatment means. Set α = 0.05.
A sample of 8 jars has a mean of 15.6 ounces and a standard deviation of 0.3 ounce. Is there enough evidence to support the consumer's conjecture at a = 0.05? First, identify the alternative and the null hypotheses.
A sample of 81 observations is selected from a normal population with a standard deviation of 5. The sample mean is 40. Determine the 95% confidence interval for the population mean.
For the new study, the estimate should be within 1% of the population proportion with a 90 percent confidence level. What is the necessary sample size?
What is the probability that a simple random sample of auto insurance policies will have a sample mean within $25 of the population mean for each of the following sample sizes: 30, 50, 100, and 400.
How large a sample size, n, should they recruit in order to obtain a confidence interval with margin of error ± 3% based on this prior guess?
Can we conclude, at the level of significance, that the mean lifetime of light bulbs made by this manufacturer differs from months?
If the market research gave a positive indication the price would be £35,000. If the market research gave a negative indication the price would be only £3,000.
