What is 5.8 × 10^6 mg/s in grams per minute?

1 answer:

4 0

$1g=1000mg\to1mg=0.001g\\\\1min=60s\to1s=\frac{1}{60}min\\\\5.8\times10^6\ mg/s=5.8\times10^6\times\frac{0.001}{\frac{1}{60}}\ g/min\\\\=5.8\times10^6\times0.001\times60\ g/min=(5.8\times60)\times(10^6\times0.001)\ g/min\\\\=348\times10^3\ g/min=\boxed{3.48\times10^5\ g/min}\\\\Answer:\boxed{C}$

Answer:

a) $t_{crit}= 1.34$

b) $t_{crit}=-2.539$

c) $t_{crit}=\pm 2.228$

Step-by-step explanation:

Part a

The significance level given is $\alpha=0.1$ and the degrees of freedom are given by:

$df = n-1= 15$

Since we are conducting a right tailed test we need to find a critical value on the t distirbution who accumulates 0.1 of the area in the right and we got:

$t_{crit}= 1.34$

Part b

The significance level given is $\alpha=0.01$ and the degrees of freedom are given by:

$df = n-1= 20-1=19$

Since we are conducting a left tailed test we need to find a critical value on the t distirbution who accumulates 0.01 of the area in the left and we got:

$t_{crit}=-2.539$

Part c

The significance level given is $\alpha=0.05$ and $\alpha/2 =0.025$ and the degrees of freedom are given by:

$df = n-1= 11-1=10$

Since we are conducting a two tailed test we need to find a critical value on the t distirbution who accumulates 0.025 of the area on each tail and we got:

$t_{crit}=\pm 2.228$
