betw en the sample mean and its population mean? That is, find the standard error for M. (Note: In a hypothesis test, this value is the denominator of the t statistic.) C. Based on the sample data, does the treatment have a significant effect? Use a two-tailed test with o = .05. 11. To evaluate the effect of a treatment, a sample is obtained from a population with a mean of and the treatment is administered to the individuals in 30, the sample. After treatment, the sample mean is found to be M 31.3 with a standard deviation of o 3. a. If the sample consists of n 16 individuals, are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with .05? 36 individuals, are b. If the sample consists of n the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with 05? c. Comparing your answer for parts a and b, how does the size of the sample influence the outcome of a hypothesis test? 12. To evaluate the effect of a treatment, a sample of n 8 is obtained from a population with a mean of and the treatment is administered to the individuals in 40,

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.
