Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient , 
is greater than 0.
so, ≠ - 0.9
Also, there is a deviation from absolute linearity.
So, ≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence, ≠ 0.3 .
So = 0.9

When it comes to probability, the answer is always expressed as part of a whole. With that being said, your answer for this problem can be a ratio, fraction or in percentage. Probability is the study of finding the chances or odds of an event happening with the use of statistics. You are already given the statistics of baby girls and baby boys. Note that you are asked to find the probability of the baby being a girl. So, the part here includes the 248, while the whole is 248+13 = 261. Therefore, the probability is 248/261 or 0.95 or 95%. That means that the likelihood of having a girl baby using this technique is very high.
For every 9 kids 5 are girls
there are 3 sets of 9
so 5 x 3 = 15
there are 15 girls
