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 cyclie nature of wind and meving 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 1075 om/sec. Based on long-term experience, 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 (b) Does the confidence interval indicate that the population mean wind speed is such that the sand is always moving at this site? Explain. O No. This interval indicates that the population mean wind speed is such that the sand may not always be moving at this site. O Ves. This interval indicates that the population mean wind speed is such that the sand may not always be moving at this site. O Ves. This interval indicates that the population mean wind speed is such that the sand is always moving at this site. O No. This interval indicates that the population mean wind speed is such that the sand is always moving at this site.
