Answer:
95% two-sided confidence interval on the true mean breaking strength is (94.8cm, 99.2cm)
Step-by-step explanation:
Our sample size is 11.
The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So
.
Then, we need to subtract one by the confidence level and divide by 2. So:
Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 10 and 0.025 in the two-sided t-distribution table, we have
Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So
Now, we multiply T and s
cm
For the upper end of the interval, we add the sample mean and M. So the upper end of the interval here is
cm
So
95% two-sided confidence interval on the true mean breaking strength is (94.8cm, 99.2cm).
Answer:
Rational Numbers
Step-by-step explanation:
- An integer in its most simplified form cannot be a decimal nor a fraction, meaning -4/3 nor -0.75 would work.
- A whole number is a number that is either positive or negative but cannot be a decimal in simplified form. -4/3 is -1.333.... which is less than one and negative, meaning it cannot be a whole number due to it obviously being a decimal.
- -4/3 is not a natural number as it is both a decimal and negative.
- -4/3 is not irrational because it repeats when in decimal form.
- -4/3 is rational as in decimal form it repeats and to give more information, rational numbers can be both positive and negative numbers. The 3 that repeats in the decimal form of -4/3 works as a rational number due to this.
Therefore, it would apply to the first square.
