3.60
Step-by-step explanation:
Data provided in the question:
level of significance = 0.05
Sample size , n = 25 observations
correlation coefficient, r = 0.60
Now,
The test statistic to compute whether the population correlation is zero is given using the formula :
t =
on substituting the respective values, we get
test statics , t =
or
t = 3.5968 ≈ 3.60

Step-by-step explanation:
<span>When you multiply a number by 10, 100, 1,000 and so forth, you move the decimal point to the right as many places as there are zeroes in the multiplier. When you’re multiplying, the order of the factors do not matter because you will still get the same answer. The law of grouping do not apply to multiplication.
The answers for the following numbers are:
a. 24.6 × 100 = 2,460
b. 37 × 1,000 = 3,700
c. 0.367 × 10,000 = 3,670
d. 0.005 × 100,000 = 500
