Answer:
3.30185 σ
8.7636
Step-by-step explanation:
the fromula for 100(1-α)% confidence (two sided) for σ is
√(η-1)*s^2/x^2_α/2,V σ
√(η-1)*s^2/x^2_(1-α/2,V) ∴ (v=n+1)
now data given is n = 12 and s=5.2 mg
for 99% CI ,α=0.05 and (n-1)=9 degree of freedom
from chi- square table x^2_(0.025,9)=19.02 ; x_(0.975,9)=2.7
substitute them in above expression we get
3.30185 σ
8.7636
Answer:
0.0181,0.2693,0.1092,0.4163
Step-by-step explanation:
Given that a certain tennis player makes a successful first serve 64% of the time.
Since each serve is independent of the other
X the no of serves in is Binomial with n = no of times he serves =9
and p = constant probability = 0.64
X is Bin (9,0.64)
Probability that she get in
a) all 9 serves in?
=
b) exactly 6 serves in?
P(x=6)
=
c) at least 7 serves in
=
d) no more than 6 serves in
=
