Answer:

8 dolls

Step-by-step explanation:

METHOD 1:

Step 1: Convert 25% into decimal (0.25)

Step 2: Multiply by 32 (32 × 0.25 = 8)

METHOD 2:

25% of a number will be one-fourth of that number. Divide 32 by 4 to get 8 (or multiply 32 by 1/4).

Roland was driving to campus but realized that his car is out of gas. He started driving around Syracuse looking for a gas stati

tester [92]

Answer:

Roland is right, he can be 95% sure that average gas prices have gone up since the same time last year.

Step-by-step explanation:

Let μ be average gas price around Syracuse.

Then hypotheses are:

$H_{0}:$ μ = $2.68

$H_{a}:$ μ > $2.68

Then test statistic can be calculated as:

z= $\frac{X-M}{\frac{s}{\sqrt{N} } }$ where

X is the Roland's calculated average gas prices of 50 gas stations ($2.74)

M is the average average gas prices in the entire of Syracuse last year

s is the standard deviation ($0.11)

N is the sample size(50)

Then z= $\frac{2.74-2.68}{\frac{0.11}{\sqrt{50} } }$ ≈ 3.86

Since P-value of test statistic ≈ 0.00006 <0.05 (significance level), we can reject the null hypothesis.
