Obtuse because it bigger than an acute and a right angle
Answer:
Step-by-step explanation:
Given data of x and y are tabulated and slope and intercept found out
X Y
26 540
27 555
33 575
29 577
29 606
34 661
30 738
40 804
22 496
SLOPE 15.89351852
Intercept 140.0833333
a) Regression equation is
y =15.89x+140.08
b) Enclosed
c) POsitive linear relation
d) When x increses by 1 unit y increases by 15.89 units
e) predictor is x and response is y
f) No outliers.Potential are
26 540
27 555
33 575
29 577
g) whenever we have x value we substitute in regression equation and find y

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
Answer:
Anthony teaches a pottery painting class in order to save up money for a nice
bike. In yesterday's class, 5 of the 11 students painted piggy banks.
If Anthony randomly chose 4 of the pieces of pottery to glaze, fire, and set on
the top shelf in a certain order, what is the probability that just the first 2 of the
chosen pieces of pottery are piggy banks?
