a. Which graph below shows a scatter plot for these data? O A. O B. OD. Ay 20- Ay 20- 10+ 10- 10+ 04 10 10- There appears to be linear relationship between x and y. b. What is the correlation coefficient for these sample data? =(Round to two decimal places as needed.) c. What are the appropriate hypotheses to test for a negative correlation coefficient? O A. Ho: ps0 HA: p>0 O B. Ho: p+0 Hai p= 0 O C. H ρ20 HẠi p<0 O D. Ho: p<0 Ha: p20 O E. Ho: p>0 HA: ps0 O F. Ho: p= 0 HA: p#0 Calculate the t-test statistic for correlation. t= (Round to four decimal places as needed.) Determine the critical value(s) for the rejection region for the test statistic t. Select the correct choice below and fill in the answer box to complete your choice. (Round to four decimal places as needed.) OA. to.05 = - OB. to.05 OC. to.025 Since the test statistic V in the rejection region, the null hypothesis. The data V support the contention that the population correlatic coefficient is negative.
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.
Make sure to do the rounding and double check the Answers please.
