NOTE: As per the guidelines, only first three subparts have been solved here Given information: A poll of 1350 adults were asked in a poll that how much confidence they had in banks. A total of 203 adults said that they had a great deal of confidence in banks. Therefore, the sample parameters are: n=1350X=203 where, n is the sample size and X is the number of people who said that they have a great deal of confidence in the banks. The economists claims that the population proportion p of adults that said they have great deal of confidence in the banks is less than 15%. The test if performed at 0.01 level of significance.1) Since it is claimed that less than 15% of US adults have a great deal of confidence in the banks, therefore, the alternative hypothesis is framed accordingly. In contrast, the null hypothesis is stated. The null and the alternate hypothesis for testing the claim is: Ho: p=0.15Ha: p<0.15 2) The sample proportion is computed as, p^=Xn=2031350=0.1504 The test statistic for testing is computed as: Z=p^-pp×1-pn=0.1504-0.150.15×1-0.151350=0.0412 Thus, the calculated z-test statistic is 0.0412.3) The critical value for left-tailed tabulated value z at 0.01 level of significance is -2.33.Since the calculated value of the z test statistic is not less than the tabulated value of z at 0.01 level of significance, therefore, Ho could not be rejected and thus, accepted. Hence, there is enough evidence to conclude that the population proportion p of adults that said they have a great deal of confidence in the banks is not less than 15%.

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.
