126 note that these participants all said they would pay not to receive the shock in an earlier portion of the study! Is there sigmificant evidence that men have a harder time sitting alone with their thoughts (i.e administered more shocks) than women? (a) State the hypotheses for the test. (b) Calculate the test statistic. (c) Find and interpret the p-value. (d) State the conclusion of the test. (e) Based on the conclusion, do you expect a confidence interval to contain zero? Explain without constructing the interval. 104. Referring back to the interesting series of tests by Wilson et. al. in Science 2014, participants were asked to sit alone with their thoughts for 15 minutes. Researchers wondered if it was hard for participants to sit alone with their thoughts because of the unfamiliar laboratory setting. Therefore, some subjects were allowed to complete the experiment at home. The 146 partici- pants completing the experiment in the lab had a mean "enjoyment score" of 5.12 with standard deviation 1.77. The 44 participants completing the experiment from home had a mean "en- joyment score" of 4.35 with standard deviation 1.95. Is there significant evidence to conclude that environment (home vs. lab) caused a difference in mean enjoyment score? Perform the appropriate test.

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.
