Use z scores to compare the given values.   Based on sample​ data, newborn males have weights with a mean of 3234.3 g and a standard deviation of 544.6 g. Newborn females have weights with a mean of 3036.7 g and a standard deviation of 598.7 g. Who has the weight that is more extreme relative to the group from which they​ came: a male who weighs 1700 g or a female who weighs 1700 ​g? Since the z score for the male is z=nothing and the z score for the female is z=nothing​, the ▼   male female has the weight that is more extreme. ​(Round to two decimal​ places.)

A. What's the standard deviation for data set 1. B. What's the standard deviation for data set 2. C. What's the standard deviation for data set 3.

Answer the question by recalling significantly low or high values based on standard deviation. Focus groups of 11 people are randomly selected to discuss products of the Yummy Company. It is determined that the mean number (per group) who recognize the Yummy brand name is 7.8, and the standard deviation is 0.97.  Would it be significantly low to randomly select 11 people and find that fewer than 4 recognize the Yummy brand name?

compare ihe altenuance al lNe res for a Saturday evening performance. He knows the mean and standard deviations for each theatre's usual attendance. Since the theatres have different seating capacity, he wants to use their relative measure of attendance as the basis for comparison. Using the information in the table below, which theatre has the relatively better attendance for a Saturday evening performance? Goodman Steppenwolf 454 Attendance 417 Mean St.dev. 383 34 438 20 a) What is Goodman's z-score? b) What is Steppenwolf's z-score? c) Which has better attendance?

Find the range, variance, and standard deviation for the given sample data, if possible. If the measures of variation can be obtained for these values, do the results make sense? Biologists conducted experiments to determine whether a deficiency of carbon dioxide in the soil affects the phenotypes of peas. Listed below are the phenotype codes, where 1 = smooth-yellow, 2 = smooth-green, 3= wrinkled yellow, and 4= wrinkled-green. 2 1 3 1 4 1 3 1 2 2 2 1 1 2 2 3 2 2 2 2 Can the range of the sample data be obtained for these values? Choose the correct answer below and, if necessary, fill in the answer box within your choice. A. The range of the sample data is 3. (Type an integer or a decimal. Do not round.) OB. The range of the sample data cannot be calculated. Can the standard deviation of the sample data be obtained for these values? Choose the correct answer below and, if necessary, fill in the answer box within your choice. A. The standard deviation of the sample data is 0.8. (Round to…

3. Use the following information about the heights measured in feet of a sample of 40 Ponderosa Pine trees and 40 Eastern White Pine trees. Ponderosa Pine Trees: Mean of 77.5 ft with a standard deviation of 11.55 ft Eastern White Pine Trees: Mean of 67.25 ft with a standard deviation of 10.33 ft Is it more unusual for a Ponderosa Pine tree to have a height of 71 ft or an Eastern White Pine tree to have a height of 71 ft relative to the data of each species of tree? Use z-scores to explain your solution.

The University of Montana admission standards require students to have an ACT score of at least 22. We know that Montana ACT scores are normally distributed with a mean of 20.1 and a standard deviation of 4. A: Students in Oregon have a mean ACT score of 21.1 with a standard deviation of 2.8. If we chose one student each at random from Oregon and from Montana, which student would be more likely to meet the ACT requirements of the University of Montana? Explain your answer using the appropriate statistics and a correctly labeled and shaded normal distribution. B: We know that the Montana ACT scores are normally distributed with a mean of 20.1 and a standard deviation of 4. Assume that the top 2% of individuals in the state are eligible for a state-funded scholarship. What score does an individual need on the ACT to be eligible? Explain your answer using the appropriate statistics and a correctly labeled and shaded normal distribution

The average McDonald's restaurant generates $3.6 million in sales each year with a standard deviation of 0.9. Trent wants to know if the average sales generated by McDonald's restaurants in Kentucky is different than the worldwide average. He surveys 27 restaurants in Kentucky and finds the following data (in millions of dollars): 4.1, 2.8, 4.4, 4.5, 5.3, 5, 3.7, 2.9, 3.8, 4.8, 3.6, 2.3, 3.7, 2.9, 2.9, 4, 1.1, 5.2, 2.9, 5, 4, 4, 5.9, 3.2, 2.2, 4.3, 3.8 Perform a hypothesis test using a 3% level of significance. Step 1: State the null and alternative hypotheses. Ho: [? v] ? v На: ? ? v (So we will be performing a Select an answer test.) Step 2: Assuming the null hypothesis is true, determine the features of the distribution of point estimates using the Central Limit Theorem. By the Central Limit Theorem, we know that the point estimates are Select an answer v with distribution mean and distribution standard deviation Step 3: Find the p-value of the point estimate. P( ? v ? v = P( ? ♥ ?…

Five students took a self-confidence test. Their deviation scores were –4, +3, +1, –2, and +2. Assuming that these scores com form a normaldistribution, which deviation represents the highest raw score?
