N(O2. Physicians say that the normal temperature of a person's bodyis 37°C. In a class, the temperatures (in degrees Celsius) of 10students were collected. These were: 36.8, 37.3, 36.5, 37, 37.5,37.1, 36.7, 37, 37.1, 36.9. Test the hypothesis that the students inthis class have normal body temperatures. Assume that bodytemperature is normally distributed. Use 5% level ofsignificance.PSTEP 1. Formulate the null and alternative hypotheses.Ho:Ha:STEP 2.

1. A researcher wishes to determine if the following distances (in meters) traveled by a random sample of ten world-class long jumpers are highly affected by the speed (in meters per second) at takeoff. The distances recorded from the sample long jumpers are as follows: 7.67, 8.22, 7.94, 7.16, 8.08, 7.35, 7.89, 7.76, 7.25, and 7.43. On the other hand, the speeds are recorded as follows: 8.9, 9.2, 8.1, 8.6, 9.0, 8.4, 8.8, 9.1, 8.0, and 8.2. What will be the distance, assuming that the speed is 9.4 meters per second? Round your answer to two decimal places. There is no need to place the unit. 2. A certain regression line equation has the slope equal to 720.25 and an intercept that is equal to -182.4.
