5.1 The determine the effect of two glass types and three phosphor types
on the light output of a televisions tube, light output is measured by the
current required in series with the tube to produce 30 foot-lamberts of light
output. Thus the higher the current is in microamperes, the poorer the tube is
in light output. Three observations were taken under each of the six trreatment
conditions and the experiment was completely randomized. The following data
were recorded.

Do an analysis of variance on these data and test the effect of glass type, phosphor types, and interaction on the current flow.

Kesimpulan
1.
Karena faktor P (jenis fosfor) Ftabel>Fhitung,
maka Ho diterima dan Ha ditolak. Jadi, tidak ada pengaruh yang signifikan
faktor P (jenis fosfor) terhadap cahaya televisi
2.
Karena faktor G (jenis kaca) Ftabel<Fhitung,
maka Ho ditolak dan Ha diterima. Jadi, ada pengaruh yang signifikan faktor G (jenis
kaca) terhadap cahaya televisi
3.
Karena interaksi PxG (jenis fosfor dan kaca)
Ftabel<Fhitung, maka Ho ditolak dan Ha diterima. Jadi, ada pengaruh yang
signifikan interaksi PxG (jenis fosfor dan kaca) terhadap cahaya televisi
