Subtract (3×12) from 348 to get 312. Subtract (9×12 ) from 292. B. Subtract (30×12 ) from 468 to get 108. Subtract (9×12 ) from 108. C. Subtract (20×12 ) from 468 to get 228. Subtract (10×12) from 228 to get 108. Subtract (3×12) from 108 to get 72. Subtract (6×12 ) from 72. D. Subtract (30×12 ) from 468 to get 108. Subtract (4×12) from 108 to get 60. Subtract (4×12 ) from 60.

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
