The first class in a relative frequency table is 50–59 and the corresponding relative frequency is 0.2. What does the 0.2 value indicate? Answer: ____Convert 0.2 to a % by times by 100. So 0.2 = 20%, so 20% of the data is between 50 and 59______________ 3. When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6.
The cost of a failure during a performance is $50,000. a. Calculate the reliability of each system. Which system would you recommend? b. Omar has learned that each system described above can also be purchased in a Plus configuration, where each component has an identical backup, for double the original
Data available is Plant Total Bricks produced in 50 days S (standard deviation) x̄ (mean) Memphis 7484500 3402.46 149690 Birmingham 6902350 3364.68 138047 Hypothesis test In a hypothesis test we assume Ho to be true and try to find evidence that shows otherwise. We test the claim using a level of confidence. Suppose we take 5% level of significance in this case. We choose a test statistic, choose a rejection region, test the statistic and make a conclusion. State Hypothesis Ho : µ1 - µ2 =< 10000 (µ1 and µ2 are the mean bricks produced in a day in Memphis n Birmingham plants) H1 : µ1 - µ2 > 10000 (Ho is null hypothesis and H1 is alternative hypothesis) Choosing a Test Statistic Whenever sample size is greater

MA1210 Mod3 3.1 Quadratic and Exponential Functions 1. Jerry wants to purchase some items whose cost function is C=3x+5, where x is the number of items. If Jerry spends between $50 and $80, find the minimum and maximum number of items that he can purchase. C=3x+5 X=(c-5)/3 answer: 15 items min X=(50-5)/3 x=15 25 items max X=(80-5)/3 x=25 2. A projectile follows a parabolic path whose height, in meters, is given by the function f(x) = -x2 + 2x +2.
Then compare the precision and accuracy of the data to the literature values for pre and post 1892 pennies when using various numbers of coins. Then determine the density of the coins. We will have to set up data sheetsin orders to record and calculate the data. 0% Cu, ~100% Zn 50% Cu, ~50% Zn 10% Cu, ~90% Zn 60% Cu, ~40% Zn 20% Cu, ~80% Zn 70% Cu, ~30% Zn 30% Cu, ~70% Zn 80% Cu, ~20% Zn 40% Cu, ~60% Zn 90% Cu, ~10% Zn Procedure: 1. Find the mass of the 5 dry pennies, then record the data.
Our mean is $46,020 and our standard deviation is 13.88, and our sample size is 50. To test this hypothesis, we will use a 5% rejection region and 95% confidence interval. Per the rules of hypothesis testing, we must not reject the null hypothesis if the p-value is greater than sigma (rejection region), and reject it if the p-value is less than sigma. Since our p-value for this test is 0.302 is less than sigma (1.645), we must reject the null hypothesis. There is sufficient evidence to indicate the true mean is greater than $45,000.
Macbeth by William Shakespeare Layered Curriculum Projects Due Friday, September 14, 2012 Assignment: You may choose from any of the projects/activities below, but you must choose enough activities to equal 100 points. Notice that the 50-point projects are more involved than, for example, the ones that are only worth 25 points, but you can do fewer activities with the more difficult projects. ALL WRITTEN WORK MUST BE TYPED, DOUBLESPACED, USING TIMES NEW ROMAN FONT AND STANDARD 1” MARGINS. 25 points each * Doctor’s Perspective - Write a journal entry from the doctor’s perspective reflecting on his visit to the Macbeth house. 10-15 sentences * Malcolm’s perspective- Write a journal entry from Malcolm’s perspective (after he becomes king) reflecting on the events of the play.
