Q4/ A sample of 20 specimens of soil was tested under shear, and water absorption tests. 8 of them failed in shear test, while 5 was failed in water absorption test and 2 failed in both. Find the following probabilities if a random sample is selected? 1-Failed in one of them at least? 2-Failed in one of them at most? 3-If it is failed in shear to be failed in absorption? 4-If it is good in absorption to be bad in shear?

Suppose we have a random sample of size n=100 drawn from a population with a mean of μ=50 and a standard deviation of σ=10. We want to test the null hypothesis H0: μ=48 against the alternative hypothesis H1: μ≠48 using a two-tailed test with a significance level of α=0.05. What is the decision and p-value of this hypothesis test?
Suppose a sample size of 87 was used to conduct a right tailed hypothesis test for a single population mean. The null |hypothesis was Ho: µ 45 and the sample mean was 50 and the p-value was 0.03. Then there is a 3% chance that 87 randomly selected individuals from a population with a mean of 45 and the same standard deviation would have a sample mean greater than 50. false true

V The university data center has two main computers: computer 1 and computer 2. A new routine has recently been written for computer 1 to handle its tasks, while computer 2 is still using the preexisting routine. The center wants to determine if the processing time for computer 1's tasks is now less than that of computer 2. A random sample of 11 processing times from computer 1 showed a mean of 39 seconds with a standard deviation of 19 seconds, while a random sample of 10 processing times from computer 2 (chosen independently of those for computer 1) showed a mean of 57 seconds with a standard deviation of 20 seconds. Assume that the populations of processing times are normally distributed for each of the two computers, and that the variances are equal. Can we conclude, at the 0.05 level of significance, that μ₁, the mean processing time of computer 1, is less than μ₂, the mean processing time of computer 2? Perform a one-tailed test. Then complete the parts below. Carry your…

Construct the indicated confidence interval for the difference between the two population means. Assume that the two samples are independent simple random samples selected from normally distributed populations. Also assume that the population standard deviations are equal (Η1 = Η2), so that the standard error of the difference between means is obtained by pooling the sample variances. 1) A paint manufacturer wanted to compare the drying times of two different types of paint.Independent simple random samples of 11 cans of type A and 9 cans of type B were selected andapplied to similar surfaces. The drying times, in hours, were recorded. The summary statistics areas follows.Type A Type Bx1 = 71.5 hr x2= 68.5 hrs1 = 3.4 hr s2 = 3.6 hrn1 = 11 n2 = 9a).
