The weights of a certain brand of candies are normally distributed with a mean weight of 0.8593 g and a standard deviation of 0.0525 g. A sample of these candies came from a package containing 465 candies, and the package label stated tha 397.1 the net weight is 397.1 g. (If every package has 465 candies, the mean weight of the candies must exceed GE = 0.8539 g for the net contents to weigh at least 397.1 g.) a. If 1 candy is randomly selected, find the probability that it weighs more than 0.8539 g. The probability is (Round to four decimal places as needed.)

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2900 grams and a standard deviation of 600 grams while babies born after a gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 505 grams. If a 32-week gestation period baby weighs 2575 grams and a 41-week gestation period baby weighs 2775 grams, find the corresponding z-scores. Which baby weighs less relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively less? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) O A. The baby born in week 32 weighs relatively less since its z-score, smaller than the z-score of for the baby born in week 41. OB. The baby born in week 32 weighs relatively less since its z-score, larger than the z-score of for the baby born in week 41. OC. The baby born in week 41 weighs relatively less since its z-score, larger than the…

If a 34​-week gestation period baby weighs 2275 grams and a 40​-week gestation period baby weighs 2475 ​grams, find the corresponding​ z-scores. Which baby weighs less relative to the gestation​ period?

Assume that weights of adult females are normally distributed with a mean of 79 kg and a standard deviation of 22 kg. What percentage of individual adult females have weights between 74 kg and 84 ​kg? If samples of 64 adult females are randomly selected and the mean weight is computed for each​ sample, what percentage of the sample means are between 74 kg and 84 ​kg?

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 3000 grams and a standard deviation of 1000 grams while babies born after a gestation period of 40 weeks have a mean weight of 3500 grams and a standard deviation of 545 grams. If a 35-week gestation period baby weighs 3300 grams and a 41-week gestation period baby weighs 3800 grams, find the corresponding z-scores. Which baby weighs more relative to the gestation period? ..... Find the corresponding z-scores. Which baby weighs relatively more? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) A. The baby born in week 41 weighs relatively more since its z-score, is larger than the z-score of for the baby born in week 35. O B. The baby born in week 35 weighs relatively more since its z-score, is larger than the z-score of for the baby born in week 41. C. The baby born in week 41 weighs relatively more since its z-score, is…

The weight of oranges growing in an orchard is normally distributed with a mean weight of 6.5 oz. and a standard deviation of 1 oz. Using the empirical rule, determine what interval would represent weights of the middle 99.7% of all oranges from this orchard.

Suppose a researcher wants to test if the average diastolic blood pressure in Irish-Americans is different than the average diastolic blood pressure in the general population. Note that the average diastolic blood pressure in the general population is 70 mmHG. The researcher recruits 30 Irish-Americans into this particular study and then measures each of their diastolic blood pressures (mmHG). The population of this sample has a standard deviation equal to 3.0. What is the two-sided alternative hypothesis? (in words) Group of answer choices The mean is different than 70 The mean is different than 73 The mean is greater than 70 The mean is greater than 73

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2900 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 3400 grams and a standard deviation of 535 grams. If a 35-week gestation period baby weighs 3200 grams and a 40-week gestation period baby weighs 3700 grams, find the corresponding z-scores. Which baby weighs more relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively more? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) A. The baby born in week 40 weighs relatively more since its z-score, baby born in week 35. B. The baby born in week 35 weighs relatively more since its z-score, baby born in week 40. C. The baby born in week 40 weighs relatively more since its z-score, baby born in week 35. D. The baby born in week 35 weighs relatively more since its z-score,…

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2600 grams and a standard deviation of 600 grams while babies born after a gestation period of 40 weeks have a mean weight of 2800 grams and a standard deviation of 390 grams. If a 32​-week gestation period baby weighs 2150 grams and a 40​-week gestation period baby weighs 2350 ​grams, find the corresponding​ z-scores. Which baby weighs less relative to the gestation​ period?

The weights of a certain brand of candies are normally distributed with a mean weight of 0.8607g and a standard deviation of 0.0514g. A sample of these candies came from a package containing 451​candies and the package label stated that the net weight is 385.3g.​    (If every package has 451 candies, the mean weight of the candies must exceed 385.3451=0.8543g for the net contents to weigh at least 385.3g.)   If 1 candy is randomly​ selected, find the probability that it weighs more than 0.8543g.
