Answer:
The length of cloth Geeka got is 2.32m
Step-by-step explanation:
The length Geetika got can be calculated by deducting the total length the tailor cuts from the initial length of the cloth.
Initial length of cloth = 15.40m
From the question, the tailor cuts 11m and 5cm for dress and 2m 3 cm for a shirt.
Therefore, the total length the tailor cut = 11m 5cm + 2m 3cm = 13m 8cm
NOTE: 13m 8cm = 13.08m
The length Geeka got = 15.40m - 13.08m = 2.32m
Hence, the length of cloth Geeka got is 2.32m
Answer: c. z = 1.35; Reject the null hypothesis
Step-by-step explanation:
Let 
be the average life expectancy of its batteries.
As per given , we have
Null hypothesis : 
Alternative hypothesis : 
Since 
is right-tailed and population standard deviation is also known, so we perform right-tailed z-test.
Test statistic : 
where, n= sample size
= sample mean
= Population mean
=population standard deviation
For 
, we have
Critical one-tailed test value for 0.10 significance level :
Decision : Since critical z value (1.28) < test statistic (1.35), so we reject the null hypothesis .
[When critical value is less than the test statistic value , we reject the null hypothesis .]
