(1) Use a 1% level of significance to test the claim that > 0. (Use 2 decimal places.) |x t0.04 critical t 2.353 Conclusion O Reject the null hypothesis, there is sufficient evidence that > 0. Reject the null hypothesis, there is insufficient evidence that A > 0. O Fail to reject the null hypothesis, there is insufficient evidence that > 0. O Fail to reject the null hypothesis, there is sufficient evidence that p > 0. (9) Find a 95% confidence interval for ß and interpret its meaning in terms of drift rate. (Use 2 decimal places.) lower limit upper limit Interpretation O For every day of drift, the distance drifted decreases by an amount that falls within the confidence interval. O For every day of drift, the distance drifted increases by an amount that falls within the confidence interval. O For every day of drift, the distance drifted decreases by an amount that falls outside the confidence interval. O For every day of drift, the distance drifted increases by an amount that falls outside the confidence interval. (h) Consider the following scenario. A sailboat had an accident and radioed a Mayday alert with a given latitude and longitude just before it sank. The survivors are in a small (but well provisioned) life raft drifting in the part of the Pacific Ocean under study. After 30 days, how far from the accident site should a rescue plane expect to look? (Use 2 decimal places.) km/100
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.
