They head to the kitchen to set out the mats. At the 5% significance level, there is enough evidence to conclude that the mean amount of summer rain in the northeaster US is less than 11.52 inches, on average. Determining standard error from a variance value only requires finding the square root of this number. If the mean is 20 claims and the standard . However, the variation among prices remains steady with a standard deviation of 20. The library director in Owensboro, Kentucky feels this is not true, so she asked a local college statistic class to conduct a survey. The null and alternative hypotheses are: State the Type I and Type II errors in complete sentences given the following statements.

There are formulas for the mean \(_{\hat{P}}\), and standard deviation \(_{\hat{P}}\) of the sample proportion. ), HAMLET: To reject, or not reject, that is the question: whether tis nobler in the mind to suffer the slings and arrows of outrageous statistics, or to take arms against a sea of data, and, by opposing, end them. For large samples, the sample proportion is approximately normally distributed, with mean \(_{\hat{P}}=p\) and standard deviation \(\sigma _{\hat{P}}=\sqrt{\frac{pq}{n}}\). (c) What is the optimum temperature for clam development? The Central Limit Theorem has an analogue for the population proportion \(\hat{p}\). Conduct a hypothesis test to determine if the percent at her school is less than 40%. The action you just performed triggered the security solution. ________________________________________, 5. Type I error: We conclude that the proportion is less than 11%, when it is really at least 11%. Did the class demonstrate that the percentage was higher in Owensboro, KY? When clamped, a number will either keep its own value if living in the range imposed by the two other values, take the lower value if initially lower than it, or the higher one if initially higher than it. If we go back to the original data points of how many customers the company had per month, well see that this variance is apparent.
