Answer:
1652 toys will be assembled in each hour by the company.
Step-by-step explanation:
A toy factory assembles 19824 toy castles over a period = 12 hours
We have to calculate the number of castles assembles each hour.
Number castles assembled per hour =
=
= 1652 toys
Therefore, 1652 toys will be assembled in each hour by the company.

Answer:
Th computed value of the test statistic is 3.597
Step-by-step explanation:
The null and the alternative hypothesis is as follows:
Null Hypothesis:
the population correlation coefficient is equal to zero
the population correlation coefficient is not equal to zero
The test statistics for Pearson correlation coefficient is thus computed as :
where;
r = correlation coefficient = 0.60
n = sample size = 25
So;
t = 3.597
Comparing to a critical value of t (23 degrees of freedom two-tailed value) = 2.069
Decision Rule:
Since computed value of t is greater than the critical value of t; We reject the null hypothesis and accept the alternative hypothesis.
Conclusion:
We conclude that the population correlation coefficient significantly differs from 0 at 5% (0.05) level of significance.
