Rusiness owners on Suffern Main street claim that the mean peed of automobiles traveling on their street is greater than he speed limit of 35 miles per hour. A Random sample of 100 automobiles was surveyed by a police radar operator. The sample yields a mean speed of 36 miles per hour and a standard deviation of 4 miles per hour.. Is there enough evidence to support the claim at a= 0.05 (use a P-value) %3D - alldentify the claim. Then state the null and alternative
