To test Ho: o = 70 versus H,: o<70, a random sample of sizen=28 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s = 65.8, compute the test statistic. (b) If the researcher decides to test this hypothesis at the a = 0.01 level of significance, use technology to determine the P-value. (c) Will the researcher reject the null hypothesis? (a) The test statistic is x =. (Round to two decimal places as needed.)

A researcher has a first-grade readiness test that is administered to kindergarten students and scored at the interval level. The population mean is 60, with a standard deviation of 10. He has administered it, individually, to a random sample of 58 kindergarten students in a city, M = 66, and wants to use a single-sample z test, two-tailed with α = .05, in order to see whether first-grade readiness in this city differs from the national level. Check the assumptions and decide if it is OK for him to proceed with the single-sample z test.
Based on a random sample of 25 units of product X, the average weight is 102 Ibs..., and the sample standard deviation is 10 Ibs. We would like to decide if there is enough evidence to establish that the average weight for the population of product X is greater than100 Ibs. Assume the population is normally distributed. What is the p-value for this test?
In a sample of n= 19 lichen specimens, the researchers found the mean and standard deviation of the amount of the radioactive element, cesium-137, that was present to be 0.009 and 0.005 microcurie per milliliter, respectively. Suppose the researchers want to increase the sample size in order to estimate the mean u to within 0.002 microcurie per milliliter of its true value, using a 95% confidence interval. Complete parts a through c. a. What is the confidence level desired by the researchers? The confidence level is.
An SRS of 400 high school seniors gained an average of x = 21.87 points in their second attempt at the SAT Mathematics exam. Assume that the change in score has a Normal distribution with standard deviation o = 48.66. We want to estimate the mean change in score µ in the population of all high school seniors. (a) Using the 68-95-99.7 Rule or the z-table (Table A), give a 95% confidence interval (a, b) for u based on this sample. (Enter your answers rounded to three decimal places. If you are using CrunchIt, adjust the default precision under Preferences as necessary. See the instructional video on how to adjust precision settings.) a: b: (b) Based on your confidence interval in part (a), how certain are you that the mean change in score u in the population of all high school seniors is greater than 0? O The upper endpoint of the interval is larger than 0, so we are 95% certain that the mean change in score in the population of all high school seniors is greater than 0. O We cannot be…
A researcher has tested the hypotheses H0: = 69 versus H1: < 69 at a 5% level of significance. Here denotes the average height (in inches) of an adult male resident of the United States. In order to test these hypotheses, the researcher obtained a random sample of 400 heights for adult males. The sample average height is 68.6 inches and the sample standard deviation is 5 inches. Compute the p-value.
