Question

The height of 10 strawberry plants after 60 days of sowing was observed to be 66,65,69,70,71,63,70,63 ,64 and 68 Can we conclude average height of plant is more than 65. Test at 5% level of significance.
​

Answer 1

Answer:

Step-by-step explanation:

the average height would be equal to sum of all height divided by no of observations

66+65+69+70+71+63+70+63 +64 +68=669

$\frac{669}{10}$=66.9

hence,the average is more than 65.
