The actual weights of bags of pet food are normally distributed with a mean weight of a bag of 50.0 Ib., and a standard deviation of 0.2 lb. e) If there is a 35% chance to choose a bag with weight greater or equal to X what is X2 49.4 15. and 51 ID. NJ 07:19 70. c) In a group of 250 bags, how many would you expect to weigh more than 50.3 lb.? 90.3 lb. d) If a...
Let us assume that the weights of bags of dog food are normally distributed with a mean of 50 lb and a standard deviation of 2.5 lb. (a) Describe the shape and horizontal scaling on the graph of the distribution for the population of all weights of bags of fertilizer. (b) Find the probability that the weight from a single randomly selected bag will be less than 46 lbs. Based upon your results, would it be unusual to find an...
The weights of bags are normally distributed with a mean of 15 ounces and a standard deviation of 0.85 ounce. 1) What should be a minimum weight of a bag that place it at the upper 5%? 2) What should be the largest weight of bag that place it at the bottom 10%?
Let x1, x2, x3,...,x100 denote the actual weights of 100 randomly selected bags of fertilizer. Let X be the average weight of this sample. If the expected weight of each bag is 50 lb. and the standard deviation of bag weights is known to be 1 lb., calculate the approximate value of P (49.75 ≤ X ≤ 50.25).
The weights of bags of cookies are normally distributed with a mean of 15 ounces and a standard deviation of 0.85 ounces In what weight interval should we expect to find the middle 70% of bags of cookies? Please submit work to this question.
The weights of a certain brand of candies are normally distributed with a mean weight of 0.8604 g and a standard deviation of 0.052 g. A sample of these candies came from a package containing 459 candies, and the package label stated that the net weight is 391.99. (If every package has 459 candies, the moon weight of the candies 391.9 must exceed 250 =0.8539 g for the net contents to weigh at least 391.99.) a. If 1 candy is...
Let x1, x2, . . . , x100 denote the actual net weights (in pounds) of 100 randomly selected bags of fertilizer. Suppose that the weight of a randomly selected bag has a distribution with mean 25 lb and variance 1 lb2. Let x be the sample mean weight (n = 100). (a) What is the probability that the sample mean is between 24.75 lb and 25.25 lb? (Round your answer to four decimal places.) P(24.75 ≤ x ≤ 25.25)...
The weights of bags of baby carrots are normally distributed, with a mean of 28 ounces and a standard deviation of 0.33 ounce. Bags in the upper 4.5% are too heavy and must be repackaged. What is the most a bag of baby carrots can weigh and not need to be repackaged?
The weights of bags of baby carrots are normally distributed, with a mean of 34 ounces and a standard deviation of 0.37 ounce. Bags in the upper 4.5% are too heavy and must be repackaged. What is the most a bag of baby carrots can weigh and not need to be repackaged?
The weight of bags of organic fertilizer is normally distributed with a mean of 50 pounds and a standard deviation of 1 pound. If we take a random sample of 25 bags of organic fertilizer, there is an 80% chance that their mean weight will be greater than what value? Keep 4 decimal places in intermediate calculations and report your final answer to 2 decimal places. Your Answer: Answer Question 9 (1 point) Weights of gumballs follow a normal distribution...
