The article "Snow Cover and Temperature Relationships in North America and Eurasia"† used statistical techniques to relate the a

poizon [28]

Answer:

Step-by-step explanation:

From the given information,

The ten observation data on october snow cover for Eurasia during the years is 6.5, 12.0, 14.9, 10.0, 10.7, 7.9, 21.9, 12.5, 14.5, 9.2

What would you report as a representative, or typical, value of October snow cover for this period, and what prompted your choice?

For the given data, 21.9 is an outlier, so trimmed mean would be good choice for the researcher,

Remove the smallest and the largest values to compute the trimmed mean

$\bar x = \frac{12.0+14.9+10.0+10.7+7.9+12.5+14.5+9.2}{8} \\\\=\frac{91.7}{8} \\\\=11.465$

A couple has 2 children. what is the probability that both are girls if the older of the two is a girl?

12345 [234]

Assuming that the probability of boys and girls is equal (in reality slightly more boys than girls are born), the probability is 1/2, simply because the older girl's gender is given and therefore not a part of the probability.

This question comes from the 'boy or girl paradox', a.k.a. the Mrs Smith Problem.

Mr. Hanson has 3 lemons and 1 lime in a bag. He selects one piece of fruit without looking. What is the probability that Mr. Han

zhannawk [14.2K]

The probability that Mr. Hanson will pick a lemon is d. 3/4.

3 + 1 = 4. The 3 lemons make up 3/4 of the fruit, so he has a 3/4 chance, or 75% chance of picking a lemon.

Hope I could help! Let me know if there is anything else you need!
