I have a probabilty and sample spaces geometry question. Lisa experiments with a new greeting-card design program.The program gives her background color options of blue,yellow, or pink, and text color options of gray or silver. Shewants to see how many ways she can design a card byselecting a background color and then a text color.The tree diagram represents the options for Lisa'sgreeting cards.Select the sample space that shows all of the possiblegreeting card options.O ((gray, blue), (gray, yellow), (gray, pink).(silver, blue).(silver, yellow), (silver, pink)){(blue, silver), (yellow, silver), (pink, silver)}[(blue, gray), (blue, silver), (yellow, gray),(yellow, silver),(pink, gray), (pink, silver)}[(blue, gray). (yellow, gray), (pink, gray)}BlueYellowPinkGraySilverGraySilverGraySilver

Here lisa is selecting a background color and then a text color.It means combination contains first…

A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights (in centimeters) of randomly selected presidents along with the heights of their main opponents. Complete parts (a) and (b) below. Height (cm) of President 181 175 166 189 190 176 Height (cm) of Main Opponent 171 188 164 184 195 172 a. Use the sample data with a 0.05 significance level to test the claim that for the population of heights for presidents and their main opponents, the differences have a mean greater than 0 cm. In this example, μd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the president's height minus their main opponent's height. What are the null and alternative hypotheses for the hypothesis test? 0 cm Ho: Md H₁: Md > 0 cm (Type integers or decimals. Do not round.) Identify the test statistic. t= = (Round to two decimal places as needed.)
Lan says that students’ favorite restaurants in Conway are not equally distributed between ZaZa’s, Umami, Mike’s Place, Brick and Forge, and The Pasta Grill. Nynaeve tests this claim by asking 40 students what their favorite restaurant is. Her survey results are 12 for ZaZa, 6 for Umami, 3 for Mike’s Place, 8 for Brick and Forge, and 11 for The Pasta Grill. Test the validity of Lan’s claim with a significance level of α = 0.05. [Hint: You are testing whether your data is a good fit against the presumption that all are equal.]
