It is 2.1 inches longer. Plz plz plz give me brainiest answer I only need 3 more to rank up. If u do I will show my work and show the answer as a fraction.
The constant of proportionality stays the same no matter what values the variables take, so in our example independently of the cost of the item (and of the tax value, which is dependent on the cost value).
Here the only value that does not change is the 0.007, the rate! - this is the correct answer.
Answer:
the required number of samples to contain the population mean = 136
Step-by-step explanation:
From the Empirical rule, If a data is normally distributed, then about 68% of the population lies within one standard deviation from mean.
Now, if we suppose that the mean of a normally distributed population is 300, and 200 simple random samples are drawn from the population. i.e. μ = 300
And;
Number of simple random samples: n = 200
Thus, by implication, we would expect about 68% of 200 samples confidence intervals to contain the population mean .
Hence,
Required number of samples = 68% of 200
This gives ;
0.68 x 200 = 136
Thus , the required number of samples = 136
