A district-wide test is used to measure math attitude in freshmen in high school students, with a mean of 78 and a standard devi
fiasKO [112]

Answer:

Step-by-step explanation:

Given that

Population mean \mu=78

std deviation \sigma =12  = 12

sample size n =36

Sample mean = \bar x = 85

H_0: \bar x = 85\\H_a: \bar x \neq 85

(Two tailed test)

Mean difference = 7

Std error =\frac{\sigma}{\sqrt{n} } \\=\frac{12}{6} \\=2

Since population std dev is known and n>30 we use Z test

Z statistic = \frac{7}{2} =3.5\\

p value <0.001

Since p value is <0.01, at 1% significance level, we reject H0.

There is significant difference between sample mean and population mean.
