Let 147 × 16 = 2352, from this we get if we multiply a number in the order 1,4,7 it can be integer number or a decimal number with another number digits order 1,6 it can be decimal or integer then resulting number digits order becomes 2,3,5,2. Let 147 can be written in different for using the same digits. foe example 147, 1.47.14.7,0.147,0.0147 etc
simillarly 16 can be written as 16,1.6,0.16 etc
using these numbers we can produce the result 2.352. The produt of two numbers result become a decimal number depends on the two numbers.
So we can write 1.47 × 1.6 =2.352 and 0.147 × 16 = 2.352
Answer:
There is not sufficient evidence to support a claim of linear correlation between the two variables.
Step-by-step explanation:
The data provided is as follows:
X Y
78 5.5
79 8.8
56.2 3.3
68.3 1.7
77.9 10.8
38.2 0.1
(a)
The scatter plot is attached below.
(b)
Use the Excel function: =CORREL(array1, array2) to compute the correlation coefficient, <em>r</em>.
The correlation coefficient between the number of internet users and the award winners is,
<em>r</em> = 0.797.
(c)
The test statistic value is:
The degrees of freedom is,
df = n - 2
= 6 - 2
= 4
Compute the <em>p</em>-value as follows:
*Use a <em>t</em>-table.
<em>p</em>-value = 0.057 > <em>α</em> = 0.05
The null hypothesis will not be rejected.
Thus, it can be concluded that there is not sufficient evidence to support a claim of linear correlation between the two variables.
