claim: the mean pulse rate (in beats per minute) of adult males is equal to 6969 bpm. for a random sample of 125125 adult ma

RoseWind [281]

Answer:

t=0.21

Step-by-step explanation:

Given $\bar x=69.2, s=10.9, n=125$ and a population mean $\mu=69$ .

#We state our hypothesis as:

$H_o:\mu=69\\\\H_a:\mu\neq 69$

The evidence available should validate either the null or alternative hypothesis.

#We calculate the test statistic as:

$t=\frac{\bar x-\mu_}{s/\sqrt{n}}\\\\\\=\frac{69.2-69}{10.9/\sqrt{125}}\\\\\\=0.2051$

$\approx0.21$

Hence, the test statistic is t=0.21

Step-by-step explanation:

64^1/3 (64^1/3 - 16^2/3)

= 4^(3×1/3) {4^(3×1/3) - 4^(2×2/3)}

= 4(4 - 4^4/3)

= 16 - 4^(1+4/3)

= 16 - 4^(7/3)

= -9.3984
