Answer:
The Biden administration is extending a mask mandate for airplanes and transit for 15 days, the Centers for Disease Control and Prevention said Wednesday.
The mandate was set to expire after April 18, following a one-month extension announced in March. Airlines have required masks on planes since early in the pandemic in 2020, but the Biden administration made them mandatory in early 2021.
The CDC said it is monitoring the spread of omicron, including the BA.2 subvariant.
Step-by-step explanation:
23=4 3+4+7 1/2 4/7 8/2
We know that
Jayden cleans 12 rooms in---------------> <span>6 hours
X rooms-------------------------------------> 4 hours
X=4*12/6--------> 48/6---------> 8 rooms
that means </span>Jayden cleans in 4 hours 8 rooms
Chandra cleans 12 rooms in---------------> 12 hours
X rooms-------------------------------------> 4 hours
X=4*12/12--------> 48/12---------> 4 rooms
that means Chandra cleans in 4 hours 4 rooms
the answer is
<span>Jayden = 8 blankrooms
</span><span>Chandra = 4 blankrooms</span>
The valid prediction for the mean of the population possible using these samples is C. Yes, the variation of the sample means is small
<h3>What is a sample mean?</h3>
It should be noted that a sample mean is an average of a set of data . Also, the sample mean can be used to calculate the standard deviation, central tendency, and the variance of a data set.
The sample mean can be applied to a variety of uses, including calculating population averages.
Here, the sample variance is a measure of the degree to which the numbers in a list are spread out. Here, the numbers given are close to each other.
If the numbers in a list are all close to the expected values, the variance will be small and if they are far away, the variance will be large.
Therefore, the correct option is C.
