he mi spots have a significant influence on the birds' behavior? Use a two-tailed test with a= 05. i- eye- Is this sample а. b. Compute the estimated Cohen's d to measure the uto size of the treatment effect. c. Construct the 90% confidence interval to estimate the mean amount of time spent on the plain side for the population of birds. 15. Standardized measures seem to indicate that the aver- 3ce level of anxiety has increased gradually over the past 50 years (Twenge, 2000). In the 1950s, the average score on the Child Manifest Anxiety Scale was u 15.1. A sample ofn = 16 of today's children produces a mean score of M = 23.3 with SS = 240. a. Based on the sample, has there been a significant change in the average level of anxiety since the 1950s? Use a two-tailed test with a = .01 b. Make a 90% confidence interval estimate of today's population mean level of anxiety. o c. Write a sentence that demonstrates how the outcome of the hypothesis test and the confidence interval would appear in a research report. 6. Weinstein, McDermott, and Roediger (2010) report that students who were given questions to be answered while studying new material had better scores when tested on the material compared to students who were simply given an opportunity to reread the material. In a similar study, an instructor in a large psychol- ogy class gave one m oun of 11

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.
