You wish to test the following claim (Ha) at a significance level of a=0.001. For the context of this problem, µd=µ2-µ1 where the first data set represents a pre-test and the second data set represents a post-test. Ho: µd = 0 На: ud > 0 You believe the population of difference scores is normally distributed, but you do not know the ndard deviation. You obtain the following sample of data: Pre-test Post-test Pre-test Post-test 42.1 98.4 53.4 160.6 65.4 29.4 62.5 78.6 59 44.3 -35.2 124.4 50.6 -15.8 51.3 131.5 33 121.9 51.3 |-15.1 70.9 132.8 56.7 27.5 47.4 57.3 41.6 61.8 57 107.9 64.5 110.3 52.8 -26.7 67 57.2 45.1 102.7 65.9 105.6 65 22.6 49.4 56.1 108.3 52.5 99.6 1. What is the test statistic for this sampleReport answer accurate to three decimal places.) 2. What is the p-value for this sample? (Report answer accurate to four decimal places.) 3. The p-value is... less than (or equal to) aa greater than aa 4. This test statistic leads to a decision to... O reject the null the null accept O fail to reject the null
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
