Find the interest rate r given I=$ 56,P=450 and t = 6 years , round your answer to the nearest
m_a_m_a [10]

Answer:

0.163

Step-by-step explanation:

P = I (1 + r)ᵗ

450 = 56 (1 + r)⁶

8.036 = (1 + r)⁶

log₆ 8.036 = 1 + r

log 8.036 / log 6 = 1 + r

1.163 = 1 + r

r = 0.163

A personal trainer determines that an individual will get the most benefit from a workout if they keep their heart rate at an av
Korvikt [17]

Using the confidence interval, it is found that the correct conclusion regarding the hypotheses test is given by:

Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.

<h3>What are the hypotheses tested?</h3>

At the null hypotheses, it is tested if the mean is of 150, that is:

H_0: \mu = 150

At the alternative hypotheses, it is tested if the mean is different of 150, hence:

H_0: \mu \neq 150.

The confidence interval is (158, 167). Since it does not contain 150, we reject the null hypotheses, hence the correct option is:

Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
