The total employees the company now have is 531.
Solution:
Beginning employees in a company = 450
Percentage of employees increased = 18%
Number of increased employees = 18% of 450
= 81
Total employees = Beginning employees + Increased employees
= 450 + 81
= 531
The total employees the company now have is 531.
Answer:
The null and alternative hypothesis are:
There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
Step-by-step explanation:
Consider the provided information.
The claim that the mean tornado length is greater than 2.6 miles.
If there is no statistical significance in the test then it is know as the null which is denoted by , otherwise it is known as alternative hypothesis which denoted by
.
Therefore, the required null and alternative hypothesis are:
significance level α =0.05
From the given table the test statistic T=2.230166
P-value is 0.0131
0.0131<0.05
P value is less than the significance level, so reject the null hypothesis.
There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
