Love it mate, clear and easy to understand keep it going 👍🏻

[Lewis-nbpn]

when your h1 value not equal to, would you double your calculated p value? (lecturer is doing this)

[Zammiez]

Is it legal to use the cg-50 to do greater than or equal to, it has that function.

[BAKER-ziiw]

So is it okay to think of the significance level as the cut off for that particular event happening as in this example there was a 0.048 chance off getting greater than or equal to 29 successes but we reject it as there was a less than 5% chance that would happen ?

What about upper, lower bounds and critical region?

[gracegrimwood]

why didn't you do calculations for the upper tail and lower tail?

[samsonyeung]

may I ask why P(X>=29) = 1 - P(X<=29) instead of P(X<29)

[kalashsapkota]

Sir can we use a calculator for this or should we do a continuity correction?

[oliviachillingworth]

so do we always test the observed value ? never the expected one??

[Ash-enul]

why do you not halve the 0.05 i dont understand
