$H_a : \mu_1 - \mu_2 \ne 0$

Step-by-step explanation:

Let the salted package be represented with 1 and the unsalted, 2.

So:

$\mu_1:$ Mean of salted package

$\mu_2:$ Mean of unsalted package

Considering the given options, the null hypothesis is that which contains =.

So, the null hypothesis is:

$H_0 : \mu_1 - \mu_2 = 0$

The opposite of = is $\ne$ . So, the alternate hypothesis, is that which contains $\ne$

So, the alternate hypothesis is:

$H_a : \mu_1 - \mu_2 \ne 0$

ANSWER

$1 \frac{11}{16} ounces$

EXPLANATION

It was given that,a bottle of la belle bœuf contains 3/8 ounces of perfume.

sp2606 [1]

Answer:

The answer is 1/6

Step-by-step explanation:

1/8 miles in 3/4 minutes

then, that means in 1 minute ( 1 min = 3/4 * 4/3) Emma will ride a distance of (1/8)*(4/3)= (1*4)/(8*3)= 1/6.

The answer is 1/6 (in 1 min she will ride 1/6 miles).
