In the year 2008, a real state agent earned an average of Php 40,250.00 a month. Suppose you recently selected a random sample of a 40 real state agents. You determined how much each of them earns each month. Your computations of their earnings resulted to an average of Php 40,400.00 with a standard deviation of Php 225.00 Using a= 0.01, can it be concluded that the average month earnings of a real state agent has increased? Use one population z-test/t-test. Determine a) null and alternative hypothesis b) level of significance and critical values c) value of the test statistics, decision about null hypothesis and conclusion.
A simple random sample of 50 adult females is obtained, and the white blood cell count (in cells per microliter) is measured for each of them, with these results: n = 50, sample mean = 6.889 (in million cells per microliter), s = 2.021 (in million cells per microliter). Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 8.3 (in million cells per microliter), which is often used as the upper limit of the range of normal values. What is the conclusion of the study? * 2 points A. The white blood cell count of the 50 adult females is equal to the mean of the white blood cell count of the population. B. The white blood cell count of the 50 adult females is not equal to the mean of the white blood cell count of the population. C. The white blood cell count of the 50 adult females is less than to the mean of the white blood cell count of the population. D.…

Twenty different statistic students are randomly selected. For each of them,their body temperature (° F) is measured and their head circumference (in) ismeasured. Without doing any research or calculations, estimate the value of r. Forthis sample of paired data, what does r represent?
A researcher is interested in examining the difference in the average egg incubation temperature of two lizards in North Carolina, the native green anoles versus the invasive brown anoles. To investigate this, she takes two random samples from both of the lizard populations and calculates the average egg incubation temperature, standard deviation, and sample size for each of the two samples. The average incubation temperature for the 25 sampled brown anoles is 83.2 degrees Fahrenheit, with a sample standard deviation of 20.2 degrees Fahrenheit. The average incubation temperature the 28 samples green anoles is 80.1 degrees Fahrenheit, with a sample standard deviation of 17.4 degrees Fahrenheit. She has also determined that the two samples do not exhibit strong skewness and appear approximately normal. Determine the standard error for the 99% confidence interval for the difference between the true mean incubation temperatures for the two different anole species, μ1−μ2. Give your…

An inspector of a production facility, which produces digital calculators, has collected 10 samples each contained 100 calculators. After the inspection, he found that 15 calculators were defective. Find the UCL and the LCL, by using 2-sigma (z=2). Hint: Sample size is known (n=100)and , the inspection has two possible outcomes (i.e., undefective and defective). In other words, average percentage error can be calculated. UCL=0.039, LCL= 0 UCL = -0.009, LCL = 0.039 UCL=0, LCL=0.039 Cannot be calculated UCL = 0.039, LCL = -0.009
For each item, identify if the type of sample is related or independent. Prof. Antonio believes that men are paid more than women in their university, on average. To prove this, she just randomly selected a total of 100 faculty members using STRS with sex as stratification variable and asked them of their monthly pay from their work in the university. An ophthalmologist wants to determine if specific eye exercises can improve peripheral vision. To confirm if these eye exercises are effective, he selected a random sample of 5 patients. Using a visual field test, their peripheral visions were scored before and after conducting the eye exercise program. Gorgeous believes that her favorite love team, LenKi, is more popular than their rival love team, SaBong. In order to verify this, she randomly selected 100 theaters that feature both the latest movies of the two love teams and asked for the box office earnings of the two films. A researcher wants to determine if the emotional quotient…
Only 18% of registered voters voted in the last election. Will voter participation decline for the upcoming election? Of the 354 randomly selected registered voters surveyed, 50 of them will vote in the upcoming election. What can be concluded at the αα = 0.01 level of significance? Find z= Find the p-value
For a sample of five different years from the period 1960 through 2007, it is found that U.S work stoppages involving at least 1000 workers occurred 268 times in one of these years, with 424, 235, 145, and 44 work stoppages in the other four. (a) Determine the mean, median, range and midrange (b) Calculate the mean absolute deviation. (c) Calculate the standard deviation and variance (d) Calculate the coefficient of skewness.
The sales rep of a waterbed claims that 25% of the Filipino died because of cardiovascular diseases. A researcher wants to test this claim. A hospital record shows that out of a random sample of 200 dead patients, 55 patients died because of cardiovascular diseases. Does the data provide sufficient evidence to support the claim of the sales rep? Use 0.03 level of significance.
