Step-by-step explanation:

Tito wants to buy some peanut butter to donate as much as possible.

There some brands are given with their price.

we will calculate the price of per ounce peanut butter of each brand.

A. Nutty : 12 ounces for $2.19

cost per ounce =

= $0.1825 ≈ $0.18 per ounce

B. Grandma's : 18 ounces for $2.79

cost per ounce =

= $0.155 ≈ $0.16 per ounce

C. Bee's : 0.28 ounces for $4.69

cost per ounce =

= $16.75 per ounce

D. Save-A-Lot : 40 ounces for $6.60

cost per ounce =

= $0.165 ≈ $0.17 per ounce

The lowest price is $0.16 per ounce. So he should buy Grandma's peanut butter.

A computer laboratory manager was in charge of purchasing new battery packs for her lab of laptop computers. She narrowed her ch

Tasya [4]

The information is missing. The information is :

Battery Pack model 1 Battery Pack model 2

Sample size 9 9

Sample mean 5 hours 5.5 hours

Standard deviation 1.5 hours 1.3 hours

Solution :

Given :

$n_1 = 9, x_1 = 5,s_1 = 1.5$

$n_2 = 9, x_2 = 5.5 ,s_2 = 1.3$

The null hypothesis is :

$H_0: \mu_1-\mu_2=0$

The alternate hypothesis is :

$H_a: \mu_1-\mu_2 \neq0$

Therefore, the standard error is

$SE = \sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$

$= \sqrt{\frac{1.5^2}{9}+\frac{1.3^2}{9}}$

= 0.66165

Thus the test statics is

$t=\frac{x_1-x_2}{SE}$

$t=\frac{5-5.5}{0.66165}$

= -0.756
