(Solved by Humans)-At wind speeds above 1000 centimeters per second (cm/sec),
Paper Details
?
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.?Sixty-one?wind speed readings gave an average velocity of?x?= 1075 cm/sec.?Based on long-term experience,???can be assumed to be?250?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 |
