The sign in the hotel elevator reads, "Maximum weight 1200 lbs". Suzanne weighs 60 pounds, her dad is three times her weight and her mom is twice her weight. Her sister
is 40 pounds heavier than Suzanne while her brother is 90 pounds heavier than
Suzanne. Should they all ride the elevator at the same time? Explain your answer.

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
