4. Final: A filling process is supposed to fill jars with 16 ounces of grape jelly. Specifications state that each jar must contain betweern 15.95 ounces and 16.05 ounces. A jar is selected from the process every half hour until a sample of 100 jars is obtained. When the fills of the jars are measured, it is found that x (xbar) = 16.0024 and s = .02454. Using x"(xbar) and s as point estimates of u (meu) and o (sigma), estimate the probability that a randomly selected jar will have a fill, x, and that is less than minimum reading. Assume that the process is in control and that the population of all jar fills is normally distributed. O a. .0391 O b. .0411 O c.0229 O d. .0166 O e. None of the above

The density of pure iron is 7.874 g/cm.Apiece of steel made of pure iron and other types of iron is in the shape of a rectangular pyramid. The rectangular pyramid has a base edge length of 4 cm, a base edge width of 9 cm, a height of 5 cm, and a mass of 425 g. What is the difference between the density of pure iron and the density of the steel rectangular pyramid? Round your answer to the nearest thousandth. Type your answer.

Two students have measured the temperature in the room with different devices to be 71.6 deg F and 71.72 deg F. Calculate the average of these two readings and express your result in the appropriate significant figures. 신

The object of a general chemistry experiment is to determine the amount (in millilitres [mL]) of sodium hydroxide (NaOH) solution needed to neutralize 1 g of a specified acid. This will be an exact amount, but when the experiment is run in the laboratory, variation will occur as the result of experimental error. Three titrations are made using phenolphthalein as an indicator of the neutrality of the solution (pH equals 7 for a neutral solution). The three volumes of NaOH required to attain a pH of 7 in each of the three titrations are as follows: 82.20, 75.80, and 75.34 mL. Use a 99% confidence interval to estimate the mean number of millilitres required to neutralize 1 g of the acid. (Round your answers to three decimal places.) mL to
