RStudio / null & alternate hypothesis testing - Question - The population mean µ of the full-body lengths (cm) is taken of an undisclosed species today (2020). Jack decides to compare this undisclosed species full-body lengths mean from 2020 with the mean from a decade ago. The mean full-body lengths from a decade ago is 50 cm. --- (Other information): Sample size = 38. Standard deviation = 4.5 Full-body lengths mean = 43.34cm --- (a) Hypothesis test, has the mean...

O CONFIDENCE INTERVALS AND TYPOTESE TESTING Determining null and alternativelypotheses An independent consumer group published its finding that the lifetimes of electric bulbs manufactured by BIG Corporation are approximately normally distributed with a mean of 640 days and a standard deviation of 124.5. BIG Corporation daims that the standard deviation of its electric bulbs is less than 1245 . Suppose that we want to carry out a hypothesis test to see if BIG Corporation's daim is correct. State the null...

Suppose you want to test the claim that a population mean equals 37. (a) State the null hypothesis. (b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 37. (e) State the alternative hypothesis If you belleve (based on experience or past studies) that the population mean may exceed 37.

Heights were measured for a random sample of 13 plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were 31 centimeters and 7 centimeters, respectively. Assume that the population of heights of treated plants is normally distributed with mean u. Based on the sample, can it be concluded that u is different from 30 centimeters? Use the 0.1 level of significance. Perform a two-tailed test. Then fill in the...
