What value will be stored in result in each of the following statements? result = x + y; // 12 result = z * 2; // 4 result = y / x; // 2 result = y - z; // 6 result = w % 2; // 1 5. Assuming there are no accidents or delays, the distance that a car travels down the interstate can be calculated with the following formula: Distance = Speed * Time Acar is traveling at 60 miles per hour. Design a program that displays the following: The distance the car will travel in 5 hours The distance the car will travel in 8 hours The distance the car will travel in 12 hours. .
By using the confidence interval of 99% the results are as follows: The mean wage used is $30,833.46 with a standard deviation of 16.947.10 and the sample size is 100. The lower wage is 26,468.18 and the upper wage is 35,198.744. The mean education in years used is 12.73 with a standard deviation of 2.79 and sample size of 100. The lower education in years is 12.011 and the upper education in years is 13.45. The mean age is 39.11 with a standard deviation of 12.57 and a sample size of 100.
b. The true population proportion of customers who live in an urban area exceeds 40% c. The average (mean) number of years lived in the current home is less than 13 years d. The average (mean) credit balance for suburban customers is more than $4300 I have been assigned to analyze the speculated data listed above by performing hypothesis test for each of the above situations (using the Seven elements of a Test Hypothesis with a=.05) in order to see if there is evidence to support my manager’s beliefs in each case (a-d), explain my conclusion in simple terms, compute the p-value with the interpretation, follow up with computing 95% confidence intervals for each of the variables described in a. b. c. d. along with interpreting these intervals. This paper will also include an Appendix with all the steps in hypothesis testing, as well as the confidence intervals and Minitab output In order to understand how hypothesis testing is done it is important that you know the elements of the Test of Hypothesis, and what each step means. The Seven elements of a Test of Hypothesis are: 1. Null
Fill in the blanks: 68% of her phone bills are between $________72______ and $________48______. µ=60 δ= 12 µ+δ = 72 µ-δ= 48 4) The amount of Jen’s monthly phone bill is normally distributed with a mean of $50 and a standard deviation of $10. Find the 25th percentile. 43.28 = 50 - 13.44% X= µ±zδ X=50 ± z(10) X= 50± 0.7(10) = 57 OR 43 75th and 25th 43 being lower is 25th 5) The diameters of bolts produced by a certain machine are normally distributed with a mean of 0.30 inches and a standard deviation of 0.01 inches. What percentage of bolts will have a diameter greater than 0.32 inches?
The aim of this study is to approve or reject the hypothesis being limb length (arm) is equal to 40% of a person’s height. Procedure/Experiment/Materials 1. Materials = Yard Stick, Calculator 2. 13 random subjects selected in Bio Lab 2010-51 3. Standing erect, a measurement was taken from the axillary to the longest finger tip of each subject 4.

A chi-square test for the mean scores listed in Table 1 gives the results € ÷ 2=0.107, df = 5, and p < 0.005. This means that there is a greater than 99.5% likelihood that the deviations that occur among the six years can be attributed to chance9. Therefore, the chi-square statistical test implies that it is highly probable that the observed fluctuations among the six graduating classes are not unexpected and all six classes have similar quantitative abilities at the end of eighth grade. Between the eighth-to-tenth-grade experiences of the first three classes (graduating in 2000-2002) and the latter three classes (graduating in 2003-2005), the change from biology to physics was the only significant change in the curriculum or academic program. The average percentile performance of each class, during its sophomore year, on the quantitative portion of the PSAT is listed in Table 2.
(10 pts) $90 is the interquartile range, a majority of the rooms 305-215=90 B) Based on the plot, estimate inner and outer fences. (10 pts) Inner fences are approximately 80 and 440. The outer fence is approximately 575. C) Based on the plot, what are the mild and extreme outliers? (10 pts) Mild outliers are approximately 115 and 340.
Strategy # 6 : Write memory cues on the test My specific actions: In my math class I will write equations and words that will cue information that is triggered by the cue. This will allow me to forget about those problems and focus on the problems I have the most trouble with, because
