Difference between the mean of the data, including the outlier and excluding the outlier is;
B: 0.93
<h3>Mean average</h3>
Her time in minutes for the given months are;
- January = 41.55 minutes
- July = 36. 38 minutes
- Feb = 42.51 minutes
- Aug = 38.48 minutes
- Mar = 43. 01 minutes
- Sept = 41.87 minutes
- Apr = 39. 76 minutes
- Oct = 51.32 minutes
- May = 37. 32 minutes
- Nov = 42.59 minutes
- June = 35.28 minutes
- Dec = 43.71 minutes
Looking at all the numbers, they largely range from 36 to 44 which means that the outlier is 51.32
Total number of minutes with outlier = 493.78 minutes
Number of months = 12
Thus;
Mean with outlier = 493.78/12
Mean with outlier = 41.15 minutes
Mean without outlier = (493.78 - 51.32)/(12 - 1)
Mean without outlier = 40.22 minutes
Thus;
Difference in both means = 41.15 - 40.22
Difference = 0.93

Answer:
The photosphere is the visible surface of the Sun that we are most familiar with. Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).
Answer:
It can be represented by the conditional statement:
"If it is an acute angle then the angle is less than 90°"
A conditional statement is a statement that takes the form of “If P then Q,” For P is called the hypothesis and Q is called the conclusion. Also, both P and Q are sentences.
Given the sentence: All acute angles have measures less than 90°
It can be represented by the conditional statement:
"If it is an acute angle then the angle is less than 90°"
Relative Dating; One fossil is found to be older than another fossil.
Absolute Dating; Age of a fossil is found to be 61.1 million years old.
<h3>How to classify fossils?</h3>
Relative dating is defined as the age of a rock layer (or the fossils it contains) compared to other layers. This dating can be gotten by looking at the position of rock layers. Whereas, absolute dating is the numeric age(specific age) of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating.
1. Relative Dating; One fossil is found to be older than another fossil.
This is because In an excavation of a project area, if we see a set of fossils found 5 meters down, they will be younger than fossils found 17 meters down.
2. Absolute Dating; Age of a fossil is found to be 61.1 million years old.
A fossil analyzed with radiometric dating would have undergone maybe 2 half lives of radioactive isotope.
