Answer:

H0 : μ = 24

H1 : μ < 24

Step-by-step explanation:

The claim or hypothesis to be tested in a statistical problem or analysis is the alternative hypothesis. This is usually the opposite of the Null hypothesis which is the usually the initial truth until there is significant evidence provided using statistical test to prove otherwise.

The null hypothesis, H0 in the scenario above is :

The alternative hypothesis is the claim, that is. The mean battery life not up to 24 hours ;

Tadeo is a beekeeper. The table shows the weekly number of bees producing honey in a new hive. Which expression gives the number
Afina-wow [57]

The exponential equation that gives the number of bees in week 12 is of:

y = 4(3)^{11} = 708588

<h3>What is an exponential function?</h3>

It is modeled by:

y = ab^x

In which:

  • a is the initial value.
  • b is the rate of change.

In this problem, considering that the initial week is the first, and the value triples every week, the expression for the number of bees after x weeks is given by:

y = 4(3)^{x - 1}

Hence, after 12 weeks, the expression is:

y = 4(3)^{11} = 708588
