Answer: Fraction= 3 3/4kg
Decimal= 3.75kg
Step-by-step explanation:
15 kilograms of rice are separated equally into 4 containers. To get the number of kilograms of rice are in each container, we divide the total kilograms of rice by the number of containers. This will be:
Kilograms of rice in each container=
15/4 =3 3/4kg as a fraction.
To convert the fraction to decimal, we divide 3 by 4 and add to 3. 3/4 equals 0.75. We then add 3 to 0.75. This will be:
Decimal of 3 3/4 = 3+0.75 = 3.75kg
Answer:
It might be independent t-test.
Step-by-step explanation:
Basically it is a independent t- test .Independent sample test t - test or student test is a statistical test.In this test we determine that there is a statistically significant difference between the mean when we are talking about unrelated group.
We are taking alternative and null hypothesis t- test
In null hypothesis we see that population of two unrelated groups are equal
H₀: u1 = u2
if we reject the hypothesis and accept the alternative hypothesis than population means
H₁: u1 ≠ u2
In this test we need a significance level that is also called alpha level who reject or accept the null hypothesis.
