A sample mean, sample size, and sample standard deviation are provided below. Use the one-mean t-test to perform the required hypothesis test at the 5% significance level. x:30, s-8, n:32. HOP:30, Ha:p>30 EE Click here to view a partial table of values of ta The test statistic is t Round to two decimal places as needed) The P-value is the null hypothesis. The data sufficient evidence to conclude that the mean is
Sample mean, x ̅ = 2.26 nM, sample standard deviation, s = 1.18 nM, and sample size, n = 12. in this area there is a natural amount of arsenic in snow, and researchers have established that the natural level is 1.5 nM. State the null hypothesis and the alternative hypothesis that should be used to determine if the level of arsenic concentration was (at that time) higher than the natural level of 1.5 nM. The sample size is rather...
A sample mean, sample size, and population standard deviation are given. Use the one-mean z-test to perform the required hypothesis test at the given significance level. Use the P-value approach. x̄ = 259, n = 15, σ = 19, H 0: μ = 250, Ha : μ > 250, α = 0.01
Here is an example with steps you can follow: sample size n=9, sample mean=80, sample standard deviation s=25 (population standard deviation is not known) Estimate confidence interval for population mean with confidence level 90%. Confidence Interval = Sample Mean ± Margin of Error Margin of Error = (t-value)×s/√n t-value should be taken from Appendix Table IV. For n=9 df=n-1=9-1=8 For Confidence Level 90% a = 1 - 0.90 = 0.10, a/2 = 0.10/2 = 0.05 So, we are looking for...
QUESTION 10 The sampling error is the a standard deviation multiplied by the sample size. b. same as the standard error of the mean. c, difference between the value of the sample mean and the value of the population mean. d.error caused by selecting a bad sample.
A sample mean, sample standard deviation, and sample size are given. Use the one meant test to perform the required hypothesis test about the mean, , of the population from which the sample was drawn. Use the P-value approach. Also, assess the strength of the evidence against the null hypothesis. x-22,298, s=14200, n = 17, HO: P = 30,000, Ha# 30,000 a -0.05. Test statistic: 224. P.value 0.0200. Reject the null hypothesis. There is sufficient evidence to conclude that the...
If the sample mean and sample standard deviation are the same when doing a study with an unknown mean and standard deviation of the population. What effect does increasing the sample size have on The P value and the margin of error (assuming the same confidence level)? Also, what effect does increasing the sample size have on the width of the confidence interval (assuming the same confidence level)?
A sample size of 22 with a mean of 8 and a standard deviation of 12.5 test the hypothesis that the value of the population mean is 70 against the assumption that it is more than 70. Use the 0.025 significant levels.
A sample mean, sample size, and sample standard deviation are provided below. Use the one-mean t-test to perform the required hypothesis test at the 1% significance level. x=22 s=6 n=15 H0: M=24 Ha: M<24 The test statistic is t=
A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the critical-value approach. 7. x-20.8, s-7.3>, n = 11, Ho: μ = 18.7, Ha: μ # 18.7, α = 0.05 a. Test statistic: t = 0.95. Critical values: ±1.96. Reject Ho. There is sufficient evidence to b. Test statistic: 0.95. Critical values: t = ±2.201....
