A state fisheries commission wants to estimate the number of bass caught in a given lake during a season in order to restock the lake with the appropriate number of young fish. The commission could get a fairly accurate assessment of the seasonal catch by extensive “netting sweeps" of the lake before and after a season, but this technique is much too expensive to be done routinely. Therefore, the commission samples a number of lakes and record the seasonal catch (thousands of bass per square mile of lake area) and size of lake (square miles). A simple linear regression was performed and the following R output obtained. Estimate Std.

In the US, 46.6% of all people have type O blood, 39.6% have type A blood, 10% have type B blood and 3.8% have type AB blood. A researcher wants to see if the distribution of blood type is different for millionaires. The table below shows the results of a random sample of 803 millionaires. What can be concluded at the significant level of ALPHA = 0.01. Round answers to 4 decimal places.1) State the hypotheses: 2) You drew 803 samples, and the observed frequencies are recorded below. Find the expected values. Blood Type ObservedFrequency ExpectedFrequency O 374 A 297 B 73 AB 59 The test-statistic for this data = The p-value for this sample = The p-value is greater than � less than (or equal to) � 3) Base on this, we should hypothesis As such, the final conclusion is that... Based on the sample data, there is sufficient evidence to claim that the distributions of blood types are not the same between the general population and the millionaires at…

Suppose that a set of ten measurements is drawn randomly. The sample consists of the set {1,1,0,15,2,3,4,0,1,3}. By inspection it is evident that the measurement x=15 appears unusually large in comparison to the rest of the measurements. Calculate the z-score equivalent for the measurement x=15 and determine if it is an outlier.
Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your finding to state whether or not the given r represents a significant linear correlation.

5. A landscape specialist studies the relationshipbetween early-stage (x) and late-stage (y) treeheights. Assume the SLR model. For 5 trees, with34 inches as the sample mean early-stage height,we know: sx2 = 11.5 , b0 = 36.2 , b1 = 0.9 , SSR = 40.2,and SSE = 9.8. a) Write the estimated SLR equation.b) The p-value for the SLR model utility test is 0.04.Does the evidence suggest a linear relationshipbetween early-stage and late-stage heights?Explain.c) If appropriate, predict the late-stage heightwhen the early-stage height is 35 inches.d) What percentage of variation in late-stageheight values is accounted for by the assumedrelationship with early-stage heights?
Engineers are interested in comparing the mean hydrogen production rates per day for three different heliostat sizes. From the past week’s records, the engineers obtained the amount of hydrogen produced per day for each of the three heliostat sizes. Then they computed and compared the sample means, which showed that the mean production rate per day increased with the heliostat sizes. a. Identify the type of the study describe here. b. Discuss the type of interference that can and cannot be drawn from this study.
