The answer to this would be 1. This is because you have a mixture of even and odd numbers, who do not share any multiples
Answer:
Jackson s reasoning is incorrect this because if we multiply with numbers smaller than zero what we get is a smaller number: 54•0.2=27 etc...
Answer:
The Lower bound of the confidence interval to the nearest integer = 6
Step-by-step explanation:
<u>Calculate the Lower bound of the confidence interval</u>
<em>First step : Calculate the mean and standard deviation for each groups </em>
<u>Group 1 ( group with music )</u>
N = 9
Total ( ∑x ) = 788
mean = 788 / 9 = 87.55
Variance ( s^2 ) = 39.777
s = = 6.31
<u>Group 2 ( group without music ) </u>
N = 9
∑x = 670
mean = 670 / 9 = 74.44
variance ( s^2 ) = 72.27
s = = 8.50
<em>Next : Calculate the pooled variance , standard error and confidence interval</em>
Pooled variance ( Sp^2 ) : 896.43 / 16 = 56.03
standard error : S ( M1 - M2 ) = √((56.03 / 9) + (56.03 / 9)) = 3.53
confidence interval : μ1 - μ2 = ( M1 - M2 ) ± Ts ( M1 - M2 )
= 13.1111 ± (2.12 * 3.53 )
= ( 5.630 , 20.591 )
The Lower bound of the confidence interval to the nearest integer = 6
Answer:
Mode.
Because it is used to determine the most frequently occurring item which in this case is movie.
Step-by-step explanation:
The 3 measure of central tendencies are namely;
Mean, median mode.
- Mean is defined as the average of a set of data.
- Median is the middle term of a set of data that splits that set of data into 2.
- Mode is the term that occurs most frequently in a set of data.
In this question, we want to find the movies most frequently watched.
Thus, from the definitions above earlier, it is clear that the only way to know this is using the mode.
