A gambler is trying to decide if a coin is weighted so he flips it 40 times and finds that only 24% turn up heads. From this data, it looks like the coin is weighted to turn up tails more often, but his sample could have been a random chance. Being well-initiated in the practice of statistics he decides to run a hypothesis test. (a) Complete the mathematical statement of the null hypothesis where we are taking to be the proportion of the 40 flips that turn up heads: H0 : p = _______ (b) Complete the mathematical statement of the alternative hypothesis: HA : p __________
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.
