Stels [109]

Answer:

Yes, Sample information does indicate that a 2-liter bottle of Pepsi contains more than 250 calories

Step-by-step explanation:

Null Hypothesis [H0] : u < 250

Alternate Hypothesis [H1] : u > 250 {One Tail}

t = (x' - u) / [ sd / √n ]

= (255 - 250) / (5.6 / √20)

5 / (5.6 /√20)

= 3.99

As t ie 3.99 > t value 1.65 ie for one tail 95% confidence level. So, we reject the null hypothesis & conclude that it contains more than 250 calories.

<h3>What is arithmetic?</h3>

Mathematical arithmetic is the study of the properties of the standard operations on numbers, such as addition, subtraction, multiplication, division, exponentiation, and root extraction. One of the branches of mathematics, 1a, deals with the application of addition, subtraction, multiplication, and division to nonnegative real numbers, sometimes including transfinite cardinals.

Given Data

Here, 5 in 15.2 is 1/10 times to 3.5.

The 5 in 3.5 is therefore $\frac{1}{10}$ times the 5 in 15.2, and likewise.
