His speed in miles per minute
Step-by-step explanation:
Answer:
the answer would be 135 meters
Step-by-step explanation:
If, to scale on a map, 1 centimeter is 3.5 meters, them 2 centimeters is 7 meters. so on and so forth until 30. 30 (centimeters) times 3.5 (meters) is 135. hope this helped!!!!! reply if this doesn't make sense
B. 512
C. 128
D. 256
that correspond to 80 % degree of confidence and the sample size
n=15.
χ2L= χ L 2 =
χ2R= χ R 2 =
Answer: this is very hard and i was wondering if there is more info
Step-by-step explanation:
The critical values for a Chi-square distribution with 80% confidence level and sample size of 15 (thus 14 degrees of freedom) are: χ2L = 18.475 and χ2R = 8.897.
The question is asking for the critical values for a Chi-square distribution which can be found using Chi-square tables usually found in statistics textbooks or online. The critical values refer to the boundary values for the acceptance region of a hypothesis test.
When trying to find the critical values for an 80% confidence level with 14 degrees of freedom (since degrees of freedom = n - 1 for sample, thus 15 - 1 = 14), you need the 90th percentile for the χ2L and the 10th percentile for the χ2R (since α = 20%, then α/2 = 10%).
Using a Chi-square table for these percentiles, we get:
χ2L = 18.475
χ2R = 8.897
