Answer:
Null hypothesis 
Alternative hypothesis 
Step-by-step explanation:
Consider the provided information.
The shower by an adult is 5 minutes.
The mean amount of time that college students spend in the shower is significantly different from 5 minutes. In a sample of 15 students, he found the average time was 4.29 minutes and the standard deviation was 0.75 minutes.
We need to determine the appropriate null and alternative hypotheses.
A null hypothesis is there is no statistical significance between the two variables.
An alternative hypothesis is there is a statistically significant relationship between two variables.
Therefore the required null and alternative hypothesis are:
Null hypothesis 
Alternative hypothesis 
Answer:
0.37
Step-by-step explanation:
The y-intercept is 4 because it is the only number without a variable
Steps:
Shape: Regular octagon
Solved for area
Side= 10cm
Formula: A=2(1√+2)a2
Round to the nearest tenth = 482.8
Description:
Using the formula for the area of Regular octagon ( A=2(1√+2)a2) We have to calculate the side length that is 10 cm. Your answer will equal as A≈482.84cm² after you calculate. Since it says to round to the nearest tenth your answer will come as 482.8.
Answer: A≈482.84cm²
Round to the nearest tenth = 482.8
