Assume that adults have IQ scores that are normally distributed with a mean of 102.1 and a standard deviation 16.3. Find the first quartile Q1, which is the IQ score separating the bottom 25% from the top 75%. (Hint: Draw a graph.)
Assume that Christmas trees sold in a farm have heights that are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. Find the value of the quartile Q3 (75% of trees are shorter than this height). 65.3 inches 64.3 inches 66.1 inches O 67.8 inches
Agricultural scientists are testing a new chicken feed to see whether it increases the number of eggs laid. The scientists divided a flock in half and gave half of the chickens the new feed, while the other half were given a regular feed. The eggs laid in a one-year period for a random sample of 10 chickens using the new feed and 10 chickens using the regular feed are recorded. Assume that the population standard deviation of number of eggs laid is 12 eggs per year for both groups and that the number of eggs laid per year is normally distributed. Let the chickens given the new feed be the first sample, and let the chickens given the regular feed be the second sample. The scientists conduct a two-mean hypothesis test at the 0.05 level of significance to test if there is evidence that the new feed increases the number of eggs laid. (a) Which answer choice shows the correct null and alternative hypotheses for this test? Select the correct answer below: H0:μ1=μ2;…

Test the claim that on average, heights (in feet) of oak trees in a forest are less than heights of pine trees. Use a = 0.01. It is known that tree heights follow a normal distribution, and the population standard deviation for both species is known to be 10.3 feet. The table below shows the results of two random samples. Туре 21 n Oaks 56.7 Pines 17 60.7 1. The fact that heights are known to be normally distributed is important in this test because: O this is a Z-test O both sample sizes are less than thirty O both standard deviations are less than thirty O this is a T-test The hypotheses are: O Ho:p1 2 P2; Ha:p1 µ2 O Ho:µ1 = µ2; Ha: µ1 + p2 O Ho:p = P2; Ha:p1 # P2 O Ho:pi p2 O Ho:µ1 2 H2; Ha:p < p2 2.

Experience has shown that the value of orders placed by customers of Handy Glass Pty is normally distributed, with an average order value (μ) of R10 200, and a standard deviation (σ) of R1 755. A sample of 85 orders is randomly selected.Q.2.2.1 Determine the standard error for this sample. Q.2.2.2 What is the probability that the mean value of the orders in the sample is less than R10 225? Interpret your answer.
There are frogs and koi in a pond, and the number of frogs and the number of koi in the pond are independent. Let X represent the number of frogs in any given week, and let Y represent the number of koi in any given week. X has a mean of 28 with a standard deviation of 2.7, and Y has a mean of 15 with a standard deviation of 1.6. Which answer choice correctly calculates and interprets the standard deviation of the difference, D = X - Y? = 1.05; this pond can expect the difference of frogs and koi to vary by approximately 1.05 from the mean. = 1.1; this pond can expect the difference of frogs and koi to vary by approximately 1.1 from the mean. = 3.1; this pond can expect the difference of frogs and koi to vary by approximately 3.1 from the mean. = 13; this pond can expect the difference of frogs and koi to vary by approximately 1.05 from the mean.
Use the scores to compare the given values. Based on sample data, newborn males have weights with a mean of 3278.8 g and a standard deviation of 986.2 g. Newborn females have weights with a mean of 3026.9 g and a standard deviation of 549.2 g. Who has the weight that is more extreme relative to the group from which they came: a male who weighs 1500 g or a female who weighs 1500 g? Since the Z score for the male is Z =______ and the z score for the female is z=______, the _______ has the weight that is more extreme. (Round to two decimal places.)
