Answer:
5%
Step-by-step explanation:
Hospital A (with 50 births a day), because the more births you see, the closer the proportions will be to 0.5.
Hospital B (with 10 births a day), because with fewer births there will be less variability.
The two hospitals are equally likely to record such an event, because the probability of a boy does not depend on the number of births
Answer:
no
Step-by-step explanation:
is one bigger than zero? no so one point three n is bigger
Answer:
Option d is right
Step-by-step explanation:
We know that a linear correlation is a measure of association between two variables dependent and independent variable. r always lies between -1 and 1 both inclusive. If r is nearer to 0 weak correlation and if |r| is near to 1 there is a stronger correlation.
Positive sign of r implies positive association and negative r implies negative association.
Hence out of the four options given about correlation we have
Option a is right because removal of outliers confirm accurate correlation
Option B is right because only if linear pattern is visible, correlation will be right
Option C is right because only for numerical data r can be calculated
Option d is wrong because correlation lies always between -1 and 1 both inclusive.
