Parenthesis,exponents multiplication, division , addition, and subtraction order
231*5-16+101)/4
first i'm assuming the parenthesis is over the whole thing
that the question should look like (231*5-16+101)/4
first parenthesis, 231*5=1,155
1,155-16=1,139+101= 1,240
1240/4= 310.

Answer:
Null Hypothesis, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute
Alternate Hypothesis, H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute
Step-by-step explanation:
The null hypothesis is basically the problem statement i.e
Pulse rates of men have a standard deviation equal to 10 beats per minute
Hence, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute
The alternate hypothesis will contradict or negate the null hypothesis i.e
H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute
