During a quality assurance check, the actual contents (in grams) of six containers of protein powder were recorded as 1527, 1532, 1504, 1517, 1528, and 1516. (a) Find the mean and the median of the contents. (b) The third value was incorrectly measured and is actually 1520. Find the mean and the median of the contents again. (c) Which measure of central tendency, the mean or the median, was affected more by the data entry error? ..... (a) The mean is (Round to one decimal place as needed.) The median is (Type an integer or a decimal. Do not round.) (b) The mean is (Round to one decimal place as needed.) The median is (Type an integer or a decimal. Do not round.) (c) After correcting the error, the mean by and the median by The was affected more. (Round to one decimal place as needed.)
If there is significantly more variability between samples than within samples , this tends to be indicative of : 1 use of an inefficient study design. 2. actual mean differences attributed to the factor. 3. incidental differences attributed to samplig error. 4. actual variance difference attribute to different samples.

A new process for producing a type of novolac resin is supposed to have a mean cycle time of 3.5 hours per batch. Six batches are produced, and their cycle times, in hours, were 3.45 3.47 3.57 3.52 3.40 3.63 Can you conclude that the mean cycle time is greater than 3.5 hours?
In the US, the average one-way commuting time is 26.4 minutes. Is this different in Atlanta? One survey of 35 Atlanta commuters found an average one-way commuting time of 30.7 minutes. (a) The test statistic is 1.1846. What is the meaning of this test statistic? The average error between different sample results and the hypothesized mean is 1.1846.The current sample result is 1.1846 standard errors above the hypothesized mean. The maximum error between different sample results and the hypothesized mean is 1.1846. (b) Based on the test statistic of 1.1846, what is the p-value to test if the average commuting time in Atlanta is different than the rest of the US? (4 decimals.) (c) On the basis of the above p-value, what can be said regarding a 95% confidence interval for the true average commuting time? The interval contain the value 26.4, because this value . (d) Suppose the sample size was increased to 120 Atlanta commuters, with other values remaining the same. How would…
