Remark
The short answer is you multiply 0.6 times the cm/s to get m/min.
Solve
Though you didn't ask for it, here's the way it is done. Notice that each set of brackets cancels the units of a set of brackets to the left of the set of brackets you are observing. This is called unit analysis. The answer is given below.
![\frac{18 cm}{sec} *[\frac{60 cm}{1 min}] * [\frac{1 m}{100 cm}] = 18*0.6\frac{m}{min}=10.8\frac{m}{min}](https://tex.z-dn.net/?f=%20%5Cfrac%7B18%20cm%7D%7Bsec%7D%20%2A%5B%5Cfrac%7B60%20cm%7D%7B1%20min%7D%5D%20%2A%20%5B%5Cfrac%7B1%20m%7D%7B100%20cm%7D%5D%20%3D%2018%2A0.6%5Cfrac%7Bm%7D%7Bmin%7D%3D10.8%5Cfrac%7Bm%7D%7Bmin%7D)

Multiplication and division are from left to right so whichever comes first is the one u solve first. Same with subtraction and addition
Answer:
Yes
Step-by-step explanation:
The chi-square test statistic = 24.68.
The critical value for df = 11.34.
Since the calculated value of the chi square falls in the critical region it is concluded that the two variables are dependent.
1) The null and alternative hypotheses are
H0: candy preferences of students is independent of age.
Ha: candy preferences of students is not independent of age.
As the calculated value χ² = 24.68 lies in the critical region χ² ≥χ² =11.34, null hypothesis is rejected.
Therefore, we conclude that there is not enough evidence to accept the null hypothesis .
