Calcualte and state the 95% confidence interval for the proportions of the people who ate the food on Friday. We want to know if the proportion of people who ate the food on Saturday is different than the proportion who ate the food on Sunday. Write an appropriate null and alternative hypothesis for this situation.
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.
Everyday from Friday through Sunday one weekend, a sample of 205 people were taken at a park. They were given the opportunity tro try a new food stand item, for free. The only thing is that if they didn't eat the whole thing, they would be charged $20. Below is a record of who actually agreed to it it.
Friday=74
Saturday=60
Sunday=71
We want to know if the proportion of people who ate the good on Friday is different than 1/3/ Check to see if using a hypothesis test of confidence interval would have any validity (check to see if our study can be used with our current values and
Calcualte and state the 95% confidence interval for the proportions of the people who ate the food on Friday.
We want to know if the proportion of people who ate the food on Saturday is different than the proportion who ate the food on Sunday. Write an appropriate null and alternative hypothesis for this situation.
