Complete Question
An F5 tornado is classified as having mean wind speeds greater than 261 mph. In an effort to classify a recent tornado, 20 wind speed measurements were randomly selected from within the path of the tornado. Suppose the mean wind speed for this tornado really is greater than 261 mph with a sample standard Deviation 41.09 mph. Based on the data, if we fined little to no evidence against the null hypothesis that the mean wind speed is 261 mph, we have made _______________.
Answer:
Step-by-step explanation:
From the question we are told that:
Sample size 
Population mean 
Sample mean 
Sample standard deviation 
Generally the equation t test statistics is mathematically given by
Therefore
Pvalue from table is
It would be 5.3% of a number given. But since there isn't, you would have to use X.
Answer:
Well, if we know that an obtuse angle is an angle greater than 90 degrees, and that a triangle's angles MUST sum up to 180 degrees and contain three angles. Then it logically follows that there's no way for a triangle to have 3 angles AND have two of the three be greater than or equal to 90 degrees as the remaining angle would have to be zero degrees or some "negative angle"- which I am pretty sure doesn't exist lol! As for a proof, I think you can cook up something with what I have given you so far :)
Answer:
The slope of this line is -1/2
Step-by-step explanation:
To find the slope of any equation, we need to use the slope formula.
m (slope) = (y2 - y1)/(x2 - x1)
m = (-13 - -15)/(11 - 17)
m = (-12 + 15)/(11 - 17)
m = 3/-6
m = -1/2
