WebStatistics and Probability questions and answers. A test of the hypothesis Ho:u = 50 versus Ha: u >50, a sample of n = 100 observations possessed mean x = 49.4 and the standard deviation s = 4.1. Please interpret and find the p-value for this test. The x has a straight line above the x please provide the step-by-step detail. WebSolution: 132 – 100 = 32, which is 2(16). As such, 132 is 2 standard deviations to the right of the mean. 100 – 68 = 32, which is 2(16). This means that a score of 68 is 2 standard deviations to the left of the mean. Since 68 to 132 is within 2 standard deviations of the mean, 95% of the exam participants achieved a score of between 68 and 132.

WebAlso, the data will be in the form of a frequency distribution table with classes. Thus, the formula to find the mean in assumed mean method is: M e a n, ( x ―) = a + ∑ f d i ∑ f. Here, a = assumed mean. f i = frequency of ith class. d i = x i – a = deviation of ith class. Σf i = N = Total number of observations. WebThe value of the largest observation is 100. Mean = Σ f x Σ f. ⇒ 50 = Σ f x 100. ⇒ Σ f x = 5000. It was later found that it is 110 not 100. Correct, Σ f x ′ = 5000 + 110 - 100 = 5010. Therefore, Correct Mean = Σ f x ′ Σ f = 5010 100 = 50.1. It is given that the median of 100 observations is 52. Median will remain same i.e. = 52.
