Answer:

Null hypothesis $H_0; \mu=5$

Alternative hypothesis $H_a; \mu\neq 5$

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 $H_0; \mu=5$

Alternative hypothesis $H_a; \mu\neq 5$

What function is represented in the table?

Pani-rosa [81]

Answer:

Step-by-step explanation:

an exponential function of the form

y = a $b^{x}$

to find a and b use ordered pairs from the table

using (0, 0.5 ) , then

0.5 = a $b^{0}$ [ $b^{0}$ = 1 ] , then

a = 0.5

so y = 0.5 $b^{x}$

using (1, 2 ) , then

2 = 0.5 $b^{1}$ = 0.5b ( divide both sides by 0.5 )

4 = b

then exponential function represented by the table is

y = 0.5 $(4)^{x}$

olasank [31]

Answer:

1440 different arrangements are possible.

Step-by-step explanation:

Number of arrangements of n elements:

The number of arrangements of n elements is given by:

$A_{n} = n!$

In this question:

6 couples, in which each can be positioned in 2 ways(him/her or her/him). So

$T = 2A_{6} = 2*6! = 1440$

1440 different arrangements are possible.
