Q2. The US Energy Information Administration compile data on energy consumption and publishes its findings in Residential Energy Consumption Survey: Consumption and Expenditure. In 1982, the mean energy consumed per American household was 114 million BTU. For that same year, 50 randomly selected households in the South had the following energy consumption: 130 55 45 64 155 66 60 80 102 62 58 101 75 111 151 139 81 55 66 90 97 77 51 67 125 50 136 55 83 91 54 86 100 78 93 113 111 104 96 113 96 87 129 109 69 94 99 97 83 97 Do the data provide sufficient evidence to conclude that in 1982 the mean energy consumption by southern households differed from that of all American household? Use the following steps to answer the questions:

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.
