Acomputer software package was used to calculate some numerical summaries of a sample of data. the results are displayed here: variable n mean se mean stdev variance x 74 50.247 ? 4.298 ? fill in the missing quantities. round your answers to three decimal places (e. g. 98.765). what is the estimate of the mean of the population from which this sample was drawn?

the first one

step-by-step explanation:

just id the test.

the answer that is correct is false

1. which statement below is true for hyperbolic geometry?

answer: d  

the sum of the measures of the angles in a triangle is always less than 180 degrees.

2. identify the statement that is true in spherical geometry.

answer: d  

the sum of the measures of the angles of a triangle is greater than 180.

3. what can be said about the vertices of an equilateral triangle drawn in poincaré’s system?

answer: b  

the vertices are equidistant from the center of the circle.

4. satellites sputnik, yeltsin, and plekov often temporarily line up in order in a great circle. the circumference of the earth is 24,900 miles, and the satellites orbit at about 150 miles above the surface. if, while in a great circle, sputnik is 9,000 miles from yeltsin, and yeltsin is 10,500 miles from plekov, how far apart are sputnik and plekov?

answer: b  

6,342 miles

5. identify the statement that is true in spherical geometry.

answer: d  

two distinct lines intersect in two points.
