Answer: H' : u = 46.3,
H1: u > 46.3
H1: u < 46.3
H1: u ≠ 46.3
Step-by-step explanation: Let H' represents the null hypothesis and H1 represents the alternative hypothesis.
"The mean reading comprehension scores of students using the old method has a value of 46.3"
Above is the initial claim or assertion about the mean reading comprehensive scores of students.
This is the null hypothesis.
It can be written as
H' : u = 46.3
Where u = population mean.
The alternative hypothesis is a claim in opposition to the null hypothesis.
Hence the possible alternative hypothesis to the null will be
H1: u > 46.3 ( upper tailed)
H1: u < 46.3 ( lower tailed)
H1: u ≠ 46.3 (two tailed)
