7 company wants to compare mean life-times of electric bulbs manufactured in two different plants. With independent samples of the life-times obtained from the two plants, technique be applied to test if the mean life-times of the bulbs are different. A O MANOVA BO t-Test CO Factorial ANOVA DO Discriminant Analysis E I don't know! 8 Consider a case of testing Job Satisfaction (DV) in terms of such variables as: Age (IV), Income (IV), and Autonomy (IV). One believes that Job Satisfaction depends on the other variables both directly and indirectly. Technique LA O MANCOVA BO Path Anahysis CO Principal Components Analysis DO Discriminant Analysis E OI don't know! will be most helpful in analysis of the case. 9 Suppose that a farmer wants to conduct an experiment in order to analyze effects of several different feeds (mutritional regimes) on the weight of his hogs. The farmer would use ANOVA to conduct his analysis. However, if the farmer also wanted to consider the original weights of the hogs (before the experiment), then he would use AO MANOVA BO ANCOVA CO Principal Components Analysis DO Discriminant Analysis E O I don't know! 10 A new type of corn seed has been developed and a team of agronomists wanted to determine whether there was a significant difference between the types of soils that they are planted in (loam, sandy, salty, clay) based on the yield of the crop, amount of water required and amount of herbicide needed. This case can be best handled by AO MANOVA BO ANOVA CO ANCOVA DO MANÇOVA

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.
