The mold Penicillium roqueforti is encouraged to grow in milk curds to produce the bluespotted and sharp-tasting blue cheeses. When grown on Czapek yeast autolysate agar,Penicillium roqueforti colonies grow with an average of 40 mm. in diameter. But cultivated ona malt extract agar, the penicillium colonies are expected to grow bigger. To verify this,Chatham Lurpak randomly sampled 16 Penicillium roqueforti colonies grown on petri dishesfilled with malt extract agar. The measurements of their diameters (mm.) are as follows:1. Using visual inspection with the given histogram and Q-Q Plot below, do the data showevidence that the diameter of the Penicillium roqueforti colonies grown on petri dishesfilled with malt extract agar follows the normal distribution?

ll Verizon 4:34 PM 10% O A sit.instructure.com Two different types of injection-moulding machines are used to form plastic parts. A part is considered defective if it has excessive shrinkage or is discoloured. Two random samples, each of size 300, are selected, and 14 defective parts are found in the sample from machine 1, and 8 defective parts are found in the sample from machine 2. Is it reasonable to conclude that both machines produce the same fraction of defective parts, using a = 0.05, find the value of zcalc? Please report your answer upto 2 decimal places.

A taxi company tests a random sample of 10 steel-belted radial tires of a certain brand and records the tread wear in kilometers, as shown below. 68,000 54,000 47,000 52,000 41,000 58,000 61,000 51,000 47,000 59,000 Note that the sample variance becomes c² times its original value if each observation in the sample is multiplied by c and unchanged if a constant is added to or subtracted from each value in the sample. Use these facts to find the standard deviation of this set of data by first dividing each observation by 1000 and then subtracting 50. For the data set that results from dividing each observation by 1000 and then subtracting 50, the variance is (Round to three decimal places as needed.) all Check answer

0 My colleagues are studying the morphology of Adelie penguin, specifically their flipper length. They are testing Hu=185 mm. If they reject Ho, what type of hypothesis testing error could they have made Define this type of error in a sentence. Oa. They could have made a type I (alpha) error. A type I error is when we fail to reject a false HO Ob. They could have made a type II (beta) error. A type II error is when we fail to reject a false HO c. They could have made a type I (alpha) error. A type I error is when we reject a true HO. Od. They could have made a type II (beta) error. A type II error is when we reject a true HO.
