The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. This process was repeated by 3 observers. The standard deviations of these 3 data sets were: Standard Deviation 1= 1.13, Standard Deviation 2= 1.01, Standard Deviation 3-1.38 Determine the true mean force using all pooled data (with a 95% probability). The result should look like this: True mean-mean +/- Margin of Error In the answer box, provide this...

Question 5. A random sample of 50 bottles of a brand of cough syrup is selected, and the alcohol content of each bottle is measured. Let μ be the mean alcohol content for the population of all bottles of the brand under consideration. The 95% confidence interval estimated from the data is (7.8 μ 9.4). (a) would a 90% confidence interval calculated from the same sample be wider or narrower? Explain. (b) Consider the statement: there is a 95% chance...

A pizza restaurant monitors the size (measured by the diameter) of the 10-inch pizzas that it prepares. Pizza crusts are made from doughs that are prepared and prepackaged in boxes of 15 by a supplier. Doughs are thawed and pressed in a pressing machine. The toppings are added, and the pizzas are baked. The wetness of the doughs varies from box to box, and if the dough is too wet or greasy, it is difficult to press, resulting in a...
The drying time of a certain type of paint under specified test conditions is known to be normall...
The drying time of a certain type of paint under specified test conditions is known to be normally distributed with mean value 75 min and standard deviation 9 min. Chemists have proposed a new additive designed to decrease average drying time. It is believed that drying times with this additive will remain normally distributed with σ = 9. Because of the expense associated with the additive, evidence should strongly suggest an improvement in average drying time before such a conclusion...
