In volleyball, a libero is a defensive specialist who can substitute for any back-row player but cannot attack or block the ball when it is above the net. Because of this restriction, liberos are often some of the shortest players on a team. Suppose that Jasmine wants to play volleyball in college but is worried she is too short to be seriously considered. She read online that the average libero on a college team is 65 inches tall, but she suspects that this is too low. Jasmine selects a random sample of 15 liberos on college volleyball teams. Their heights, in inches, are listed below. Assume that the height of all female liberos on college volleyball teams is normally distributed. 62, 63, 65, 66, 67, 64, 66, 67, 69, 68, 63, 65, 66, 68, 68 If you wish, you may download the data in your preferred format. CrunchIt! CSV Excel JMP Mac Text Minitab PC Text R SPSS TI Calc Jasmine decides to use a right-tailed one-sample t-test to determine whether the average height of liberos on college volleyball teams is greater than 65 in. Have the requirements for a one-sample t-test been met? If they have not been met, leave the remaining questions blank. O Yes, Jasmine selected a random sample from a normally distributed population, and her sample contains no outliers. No, Jasmine selected a normally distributed random sample, but she does not know the population standard deviation. No, Jasmine selected a random sample from a normally distributed population, but her sample is too small. Yes, Jasmine selected a random sample that is normally distributed and contains no outliers. Choose the appropriate null and alternative hypotheses for this test. Họ: H1: Ox = 65 in Ox> 65.80 in O x = 65.80 in Ou > 65 in Он 3 65 in Ou > 65.80 in µ = 65.80 in Ox> 65 in Calculate the value of the one-sample t-statistic. Give your answer precise to three decimal places. t 3D Use a t-distribution table such as this one to find a range of possible P-values for this test. 0.025 < P < 0.050 0.020 < P < 0.025 0.100 < P < 0.150 0.050 < P < 0.100 Complete the conclusion of this test. Use a significance level of a = 0.05. Jasmine should her null hypothesis. There is evidence that the mean height of liberos on college volleyball teams is 65 in.
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.
