ses are beautifu fowers found threughout the United States, Canada, and northerm Europe. This problem concerns length of the sepal (leaf-ike part covering the fower) of dmerent species of wid irs. Data are besed on information taken from an artide by R.A Fisher in Annais of Eugenics (ve. 7. part 2, sp. 179-188). Measurements of sepal length in random samples of bs setesa (). Dris versicolor (I), and Iris virginica () are as follows below. ethere are no diferences among the population means of sepal length for the dferent species of irs Use a 10 level of significance. lof significance State emate hypotheses H A three means are diferent.

An article in Electronic Components and Technology Conference (Vol. 52, 2001, pp 1167-1171) describes a study comparing single versus dual spindle saw processes copper metallized wafers. A total of nsingle = 10 devices of the single saw type and a total of ndouble = 12 devices of the double saw type were measured for the width of the backside chipouts. The sample mean chipouts for the single saw type were I sin = 68.9 with a sample standard deviation of single = 7.3. The sample mean chipouts %3D the double saw type were Idouble = 49.0 with a sample standard deviation of sdoubl 8.7. Assume that both populations are normally distributed and have the same variance Calculate the upper bound of a 95% two-sided confidence interval on the mean difference in spindle saw process where the difference is "single - double". Enter yo answer to two decimal places. Hint: The formula for a confidence interval using the pooled variance (assumes equ variances) is (a1 - T2) ±ta/2,n1+ng-2 * Sp * /1/n +…

Frog Thumb Length. W. Duellman and J. Kohler explore a new species of frog in the article “New Species of Marsupial Frog (Hylidae: Hemiphractinae: Gastrotheca) from the Yungas of Bolivia” (Journal of Herpetology, Vol. 39, No. 1, pp. 91–100). These two museum researchers collected information on the lengths and widths of different body parts for the male and female Gastrotheca piperata. Thumb length for the female Gastrotheca piperata has a mean of 6.71 mm and a standard deviation of 0.67 mm. Let x denote thumb length for a female specimen. a. Find the standardized version of x. b. Determine and interpret the z-scores for thumb lengths of 5.2 mm and 8.1 mm. Round your answers to two decimal places.

The jar contains five balls, numbered 1 to 5. A ball is drawn at random and X is the number on the ball. This is a histogram of the PDF.  Why is this false?

Three cylindrical parts are joined end to end to make up a shaft in a machine; 2 type A parts and 1 type B. The lengths of the parts vary a little, and have the distributions: A~ N (6, .4) and B~ N (35.2, .6). The overall length of the assembled shaft must lie between 46.8 and 47.5 or else the shaft has to be scrapped. Assume the lengths of different parts are independent. What percent of assembled shafts have to be scrapped?

Giant Tarantulas. One of the larger species of tarantulas is the Grammostola mollicoma, whose common name is the Brazilian giant tawny red. A tarantula has two body parts. The anterior part of the body is covered above by a shell, or carapace. From a recent article by F. Costa and F. Perez–Miles titled “Reproductive Biology of Uruguayan Theraphosids” (The Journal of Arachnology, Vol. 30, No. 3, pp. 571–587), we find that the carapace length of the adult male G. mollicoma is normally distributed with a mean of 18.14 mm and a standard deviation of 1.76 mm. Let x denote carapace length for the adult male G. mollicoma. a. Sketch the distribution of the variable x. b. Obtain the standardized version, z, of x. c. Identify and sketch the distribution of z. d. The percentage of adult male G. mollicoma that have carapace length between 16 mm and 17 mm is equal to the area under the standard normal curve between _____ and _____. e. The percentage of adult male G. mollicoma that have carapace…

How do I write a conclusion statement regarding which islands, if any, differ from one another with regard to the means of finch beak depths? I have images of my data attached

Use RCommander for code and output Define the parameter, the hypothesis, a, and compute the value of the test statistic, p-value, and state the decision and conclusion Childhood lead poisoning is a public health concern in the United States. In a certain population, 1 child in 8 has a high blood lead level (defined as 30 µg/dl or more). In a randomly chosen group of 16 children from this population, determine the following. 1. a) More than 2 but less than 6 children have high blood lead? 1. b) How many of the 16 children are expected to have high blood lead? 1. c) At least 1 child has high blood lead? 1. d) What number of children have high blood lead to reach the 80th percentile? 1. e) Exactly 2 children have high blood lead?
