The average interval for the population is expected to be 300 days, but you find that your sample has a mean interval of 290 days and a standard deviation of 50 days. The t-score is then (290â300)/(50/15^0.5) or â0.775.
It takes Mars about 687 Earth days (1.882 Earth years) to orbit the Sun.The orbital path of Mars is about twice that of Earth. Mars orbits about 227 million kilometers away from the Sun. The planet travels a distance of approximately 1.43 billion kilometers (888 million miles) in 686.971 Earth days.It takes 1.88 years for mars to make one revolution around the sun.enus orbits the sun in approximately 225 Earth days. (224.70069 days) Strange as it may seem, Venus rotates so slowly that a day on Venus is longer than its year. It take â¦ s Venus about 243 Earth days to spin once on its axis. The slow rotation is also in a retrograde (clockwise) direction, from east to west.
Since the earth and mars both orbit the sun, the distance is changing all the â¦ time. In 2003, the orbits lined up, and Mars came within 55 million kilometers. Driving your car at 50km/hr, it would take 114 years to reach Mars when it was 55 million kilometers away.n average Mars orbits the Sun at a distance of 227,939,100 km On average the Earth orbits the Sun at a distance of 149,597,888 km Thus the distance between their average orbital paths is 78,341,212 Km. However, they would actually only be this distance from one another on rare occasions.
