Answer:
Lower limit = 0.76
Upper limit = 0.84
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 350
Number of drivers that buckle = 280
Formula:
The standard deviation for sp =
95% Confidence Interval:
Putting the values, we get,
Lower limit = 0.76
Upper limit = 0.84
The temp. started at -20. If it rose +8 degrees, then it would be -20+8=-12, because since the -20 and +8 are opposites, you would subtract them and the answer would have the sign of the larger number which is -. so -12 is the answer.
Y=(11/8)x+6
subtract the 8y to the right then add the 48 to the left then divide by 8
