7.3.46-T Question Help If a random sample of 100 items is taken from a population in which the proportion of items having a desired attribute is p = 0.25, what is the probability that the proportion of successes in the sample will be less than or equal to 0.297 The probability will be (Round to four decimal places as needed.)
X 7.3.46-T Question Help If a random sample of 100 items is taken from a population in which the proportion of items having a desired attribute is p=0.35, what is the probability that the proportion of successes in the sample will be less than or equal to 0.427 The probability will be (Round to four decimal places as needed.)
A random sample of n=250 measurements is drawn from a binomial population with probability of success .85. a). Find E(pˆ) and σ(pˆ). b). Describe the shape of the sampling distribution of pˆ. c). Find P(pˆ<.9).
a sample of 200 is drawn from a population with a proportion equal to .25. determine the probability of observing between 41 and 63 successes
Suppose a random sample of 100 observations from a binomial population gives a value of p = 0.45 and you wish to test the null hypothesis that the population parameter p is equal to 0.40 against the alternative hypothesis that p is greater than 0.40. Complete parts a through c. a. Noting that p = 0.45, what does your intuition tell you? Does the value of p appear to contradict the null hypothesis? O A. Yes, because p satisfies Hg:p>0.40...
A random sample of n = 400 observations from a binomial population produced x = 133 successes. Give the best point estimate for the binomial proportion p. (Round your answer to three decimal places.) p̂ = Calculate the 95% margin of error. (Round your answer to three decimal places.) ______
A random sample of n = 900 observations from a binomial population produced x = 655 successes. Estimate the population proportion p and calculate the margin of error. (Please note, your estimate is a point estimate, and the margin of error is 1.96 x S.E.)
A population proportion is 0.4 A sample of size 250 will be taken and the sample proportion will be used to estimate the population proportion. Use z-table. Round your answers to four decimal places. Do not round intermediate calculations. a. What is the probability that the sample proportion will be within +- .04 of the population proportion? b. What is the probability that the sample proportion will be within +- .06 of the population proportion?
A random sample of n = 200 observations from a binomial population produced x = 190 successes. Find a 90% confidence interval for p. (Round your answers to three decimal places.) _______ to _______ Interpret the interval. 90% of all values will fall within the interval. There is a 10% chance that an individual sample proportion will fall within the interval. There is a 90% chance that an individual sample proportion will fall within the interval. In repeated sampling, 90%...
